How to make light for movement. Connecting a motion sensor for lighting - instructions. How the device works

Before moving on to the instructions for connecting a motion sensor for lighting with your own hands, I would like to note that the device in question is not the same as the one we already discussed in the previous article. This product is designed to instantly turn on the light when any object enters the detection zone. We'll talk further about how to install and connect the motion sensor yourself!

What is the working principle?

Many people wonder how exactly this detector works. So that readers of "" are fully aware, let's first quickly go over the basic principle of the sensor.

The operation and inclusion of the lamp will depend on what type of detector you have chosen. Today there are the following types of motion sensors for lighting:

• sound - triggered by the noise level in the detection zone;
• oscillatory - they close the circuit if they detect a moving object nearby;
• infrared - react to heat.

For outdoor use, it is best to install a second version of the motion sensor, which is also suitable for use in an apartment (entrance). The remaining two options are more often used in security systems. As for the principle of operation itself, everything is not complicated - when an object is detected (either a sound or an increase in temperature), the detector sends a signal, as a result of which the relay closes the circuit and the light bulb turns on.

By the way, you can make a simple detector with your own hands, if, of course, you have the slightest skills in working with a soldering iron. If you are interested in creating such useful homemade product, we recommend watching the video lesson provided below.

Making a detector with your own hands

Methods of connecting to the network

The second, important nuance that you should know is the diagram for connecting the motion sensor to the lighting. Today, the device can be connected directly to the luminaire, through a regular switch, or in combination with another detector installed in another location.

We bring to your attention all four options for wiring the wires to the terminals:

By the way, it is not at all necessary to draw a new line from distribution box, creating additional grooves in the wall. The light control device can be connected to an outlet by connecting an electrical cord with a plug, or it can be “embedded” directly into the connection point of the chandelier to the electrical network. There are also modern models battery operated (wireless).

As for the first connection diagram for a motion sensor, it is the simplest, but at the same time the least convenient for use in a house or apartment, because The light will only turn on when detection occurs. The second option is more convenient, because it becomes possible to switch the circuit to a regular key switch. In this case, the current will bypass the detector, which will make the lighting in the room constant until the switch manually opens the circuit.

Electrical circuit c is used if you decide to connect powerful light sources to the detector, for example, several spotlights. The fact is that one of the characteristics of the sensor is the rated power, which most often varies from 500 to 1000 W. If total power There are more light sources than in the specifications, it is necessary to add a magnetic starter to the circuit.

The latter connection scheme is used if it is necessary to monitor a spacious room or a winding corridor. This is due to the fact that the maximum coverage area of ​​a conventional device does not exceed 12 meters (expensive modern models can detect an object within 20 meters). If you want to monitor a large area, for example, a garden in a country house, which will be illuminated by a street lamp, one detector will not be enough and the area will only be partially under control. The same situation applies to a winding corridor in which you decide to install a motion sensor for lighting. Every turn is an obstacle beyond which control will not be carried out. That is why, in order for the device to trigger and, accordingly, turn on the light, it is necessary to connect detectors at several points.

Installation instructions

WITH wiring diagram and we figured out the principle of operation of the device. The last and most important thing left is to provide technology for connecting a motion sensor for lighting.

So, to connect a motion sensor to a 220 V network with your own hands, you must complete the following steps:

That's all step-by-step instruction on installing the detector! We hope that now you know how to install and connect a motion sensor for lighting with your own hands! So that you can clearly see the essence of the event, we provide this video instruction.

The motion sensor is used for automatic switching on light in the house. It detects an object moving in the room and sends a signal to turn on the light. It is very convenient to use such devices in everyday life.

What is a motion sensor and why is it needed?

The motion sensor is a special wave detector powered by electricity. It detects movements in the room. That is, any moving object entering the coverage area of ​​the motion sensor activates the sensor system, which transmits it to the mechanism attached to it.

The device will not harm your health and will significantly save energy, and therefore the money that you could pay for it.

This device has many advantages:

By installing a motion sensor in any warehouse, will make your life easier. As a rule, in such rooms the switches are located quite far from the entrance. This means that if the room is creatively cluttered, you can easily get injured by tripping over an object.

Multifunctionality is one of the main advantages of motion sensors. Not only is it compact and ideal for any interior, but it can also be wireless, which is convenient. The motion sensor can be used for various purposes, be it opening a gate or signaling.

Types of motion sensors

Now there are several types of motion sensors. Before purchasing, you should understand a little about the characteristics of these devices. Their a large number of so that everyone can choose a device that suits their specific requirements.

Motion sensors are divided into several types, depending on the location where it is located:

• Type internal. This type of sensor is located indoors. You can install it absolutely anywhere in your house or apartment.
• External type. Such a device operates at a distance of 100 to 500 meters. They are usually installed in the courtyard of a house or in large areas of various industries.

The installation, like the devices, is divided into two types:

• Ceiling installation type. This alarm device is mounted in the ceiling. Typically, it works 360 degrees.
• Wall-mounted or, another name, corner type of installation. The advantage is considered to be a smaller opening angle, which reduces the number of false reactions.

The power supply of the alarm is divided into several types:

Wired power supply – they work well throughout the entire period of operation, almost like new. This happens because electricity is transmitted through wires. The alarm has a minus - it turns off if there is no electricity.

Autonomous or wireless power supply. It runs on one or more batteries that are pre-built. More modern models are powered sunlight. However, such an environmentally friendly option requires control of electricity. It should not be too little or too much.

Installation

The sensors also differ in installation. There are external or overhead ones, as well as devices that are built-in. The first ones are easy to install; you only need to connect electrical wiring to them. The second type has the main advantage of being able to be manufactured for the interior and overall design rooms.

To better understand what it looks like, it’s worth looking at photos of such motion sensors. Thanks to this advantage The sensor can be planned at the design stage of the whole house project. Both types differ from each other in their operating principle.

Ultrasonic motion sensor

It works quite simply. The waves that come from the moving object are read by a built-in wave catcher. This type of sensor lasts a long time and is easy to use. The price of the ultrasonic sensor is reasonable and it is also environmentally friendly.

However, it has some disadvantages:

• Often does not respond to slow moving objects.
• It has a negative effect on animals, so if you have pets you should not choose a sensor of this type.

Infrared sensors

Such devices react to heat emanating from a moving object, then the light turns on. The implementation of this action directly depends on the number of light bulbs that are built into the system. The more lamps, the more territory the device covers.

It is not advisable to install such a sensor in the kitchen, because... there are temperature changes, and as you already know, these devices do not like temperature changes.

The sensor is harmless to animals and people. The device is customized to suit your viewing angle and sensitivity requirements. Sensors of this type work great both indoors and outdoors - this is definitely a plus. Infrared sensors include 12 volt motion sensors.

Minuses infrared sensors:

• They react to heat waves from equipment located in the room.
• Precipitation and sun affect the infrared sensors.
• Does not react to objects that do not emit heat.

Principles of operation of motion sensors

The principle of operation of the motion sensor is quite simple. When a moving object appears in the motion sensor's viewing area, the built-in detector will turn on the relay and with its help, electricity will be transmitted to the light bulbs, thereby turning on the light.

The device operates for the time you specify in the settings. You can select from 5 seconds to 10 minutes. That is, for example, you set a timer for 5 minutes, if there is no movement during this entire time, the device will turn off the light.

Even before purchasing a sensor, you need to decide on its location. The type of device will depend on this. For example, an infrared sensor will not respond to a person if he has not entered the room. If you want the light to turn on when the doors are opened, install an ultrasonic type device.

How to install a motion sensor correctly?

You already know what a motion sensor is, their types, and how they work. Now let's talk about how to properly connect a motion sensor. When placing the device, be sure to take into account the size of the room where the windows and doors are located. All this affects the correct operation of the sensor.

Consider these factors when installing the device:

• There should be no dirt or dust.
• Any objects in front of the sensor, especially outdoors, can cause the device to trigger.
• If you are installing an alarm with wiring, its insulation must be moisture resistant.
• Mounting the sensor next to or opposite devices that emit light or electromagnetic waves is not a good idea.
• Set desired angle and direction, because the device will react to objects that fall within the coverage area.
• Select lamps according to power, take with a margin of 15%.

So now you know everything there is to know about motion sensors. I hope after reading this article, you have decided for yourself which motion sensor is better to choose.

Photos of motion sensors

Today, street lighting is of interest mainly to residents of the private sector or holiday villages. For apartment buildings Street lighting is handled by city services.

But for summer residents and people living in private houses, great solution There will be an installation of a street motion sensor to automatically turn on the lights in the garden plot.

Such a street device is practically irreplaceable; it immediately solves several problems, not only regarding street lighting, but also the possibility of protecting private property.

Range of choice

Today there is a tendency towards increasing penetration into our daily life all kinds of technical innovations. Thus, sensors that respond to motion are increasingly appearing in our homes and on the streets. Using such devices, you can automate the process of lighting any room or street.

Sensor response to various kinds movement is widely used on the streets of cities and villages. This allows you to make movement on streets and roads safer and more comfortable.

This sensor is a small plastic device that can be installed on the street almost anywhere.

Note! The choice of location should be made based on the requirements of the device. The motion sensor must have a wide range of operation in order to adequately and fully perform its functions of switching on Sveta.

Instrument placement

All street sensors, responding to various types of movements, belong to external devices. They can only be installed outdoors. Therefore, unlike internal devices, can withstand low temperatures.

Outdoor equipment of this kind, unlike indoor sensors, has an increased angular coverage of 180 degrees.

A sensor for turning on street lights, just like internal devices, can be of the following types:

Microwave, Ultrasonic,
Infrared

• microwave. The device captures a signal in a certain range like a locator;

• ultrasonic. Its operating principle is to detect changes in the reflection of ultrasound from objects. In terms of its organization, it is recognized as the most accessible and simple;

• infrared. It works on the principle of a sensitive thermometer and responds to changes in temperature in the serviced area. It can be adjusted to human body temperature, which will avoid possible activation of the device when passing near a pet.

On the electronic device market you can find two types of infrared motion sensors for turning on street lights:

• active. Such a sensor is very often used for lighting and protecting the perimeter of a house, as well as a fence;
• passive. This type The device is better suited for protecting wide areas. They are placed in front front door or at the gate.

It is also necessary to know that sensors for turning on street lights when movement occurs in the area of ​​their operation may vary depending on the installation location:

• ceiling;
• wall

As you can see, the range of choice is quite large. Therefore, when purchasing a device, you should think through all the details of its further use and placement in order to buy what you need.

Selection options

To do right choice The entire available range should be assessed according to the following indicators:

• location;
• fastening method;
• degree of security;
• power and range of equipment;
• dimensions and dimensions;
• the boundaries within which the signal should be triggered;

Note! It is important to remember that the motion sensor can only monitor the area it can see. At the same time, any light structures, of which there are plenty on the street, can reduce the viewing radius: a cornice, a fence element, hanging lamp etc.

• the ability to fine-tune the operating parameters of the device. Interestingly, some sensors can even be triggered by human breathing.

In addition, the choice should be made based on the following parameters:

Device placement

• high quality lighting. There should be just enough light to illuminate the required area;
• speed of turning on the lighting in the presence of movement;
• aesthetic lighting and appearance device;
• durability.

Having assessed the available offer on the market or a specialized store according to the above parameters, your choice will be the most optimal and will fully satisfy all your needs.

It is important to note that the sensor must be able to connect not only to lighting fixture, but also to other equipment, for example, to sound equipment. This is especially important for the street, since as a result you will not only get the lights automatically turned on at night, but also an alarm.

Where are they used?

The main purpose of a motion sensor, as you might guess, is to turn on the lights on the street at night. This function is very popular in the following situations:

• in holiday villages where there are problems with street lighting by local authorities;
• lighting personal plot at night, without the need for mechanical connection of lighting;
• lighting in hard to reach places buildings remote from the main house;
• as a device that informs about the entry of strangers into the territory. In this case, the sensor turns on the light and activates the sound signal;
• lighting of storage rooms, garages and other outbuildings.

In addition, automating the switching on of lighting when there is movement in a given area allows you to save energy. And this is very important, because in Lately the electricity bill is increasing.

How the device works

As noted above, the principle of operation of the motion sensor is that the device reads a certain signal, depending on the model, and closes the electrical circuit, which leads to the light turning on.

Principle of operation

The operating algorithm of the device consists of the following stages:

• the device reads signals coming from the controlled area;
• when changes (movement) are detected, the signal enters the capturing matrix, and the device closes the electrical circuit;

Note! A special capturing matrix - a Fresnel lens (photocell) - can act as a signal receiving sensor.

• closing the circuit turns on the light.

Any street sensor for detecting movement and turning on lighting works on the principle of continuous monitoring of the selected viewing area.

All street motion sensors operate on this principle. Moreover, each device can be configured individually, which eliminates the possibility of it being activated by pets. But in this case, you should remember that the light can be turned on by vehicles passing by or just a passerby.

Separately, it is worth noting that during its operation, the street sensor also checks the level of illumination of the controlled space. So, if movement was detected during daylight hours, the light will not turn on.

Having an assessment of the controlled area for illumination allows you to save energy and gain automatic lighting only when needed - at night. At the same time, false alarms of the sensor can be minimized as much as possible with the help of correct settings.

Settings

Motion sensors are adjusted using special potentiometers, which come in three types:

• time. That is, this is the time interval during which the device will operate. Typically this parameter is set in the range of 5-10 s. Correctly selected delay time will avoid unnecessary activation of equipment. The time interval depends on the model purchased;
• sensitivity. The speed of the equipment’s reaction to movement in the control zone depends on how much higher this parameter is. In a situation where frequent idle triggering occurs, the sensitivity of the sensor should be reduced. In order to determine the desired sensitivity of the equipment, an average of three adjustments are necessary;

Note! Sensitivity adjustments are made depending on the time of year.

• illumination level. You select the level of illumination to which the device will respond by turning on.

Having made the correct settings, the sensor will operate without failure, just like a clock.

Installation of the device

Street sensor connects to the electrical network in the same way as a conventional switch. It is better to have professionals handle the connection, but you can do it yourself if you understand electricity.

The connection procedure is as follows:

• turn off the electricity;
• open the device by removing the protective cover;
• connect according to the required diagram;

Connection diagram

• connect the cable from the sensor to general wiring Houses. The connection takes place through a junction box;
• After that, we install sensors that respond to light levels. In everyday life they are called twilight switches. After connecting and setting them up, the device will only operate at night.

As you can see, the choice of street sensors that respond to movement by turning on the lights is quite extensive and requires scrupulousness. But then you will be able to fully appreciate its advantages and comfort from automated connection Sveta. But do not forget that the key to success here is not only the right choice, but also proper installation.

Homemade switching power supplies with regulators Overview and connection of the electrical panel for external lighting devices

By connecting a motion sensor to a lamp or lamp, people avoid high energy costs and, consequently, pay for utility service few. A device that records the movement of objects is convenient device, because it provides a unique opportunity to turn the light on and off automatically.

Operating principle and use of the sensor

A motion sensor is a device that “notices” changes in the location of objects in space and reacts by triggering the necessary actions. If the device is connected to an electrical system, then in response to human movement, the sensor closes the circuit and produces light. This reaction is the result of a transformation of the thermal field, because its temperature rises due to air fluctuations.

The device resembles a regular switch

However, the principle of operation of the motion sensor may be different. Therefore, the device can be infrared, ultrasonic, microwave and combined. Only the infrared sensor reacts to changes in the warm field. Ultrasonic and microwave devices operate by producing sound vibrations. The sensor that detects ultrasound is considered the most advanced, as it scans movements even through walls. The combined device detects several types of radiation.

A device that records movements is used as a device that helps save on electricity. But the sensor is good not only because it turns off the lights if the owner of the house and children running from one room to another forget to do so. The device eliminates the need to feel for the switch in the evening and at night or allows you to completely abandon the switching device that supplies current.

When your hands are busy, you can't do without turning on the lights automatically.

Choosing a location for the device

In order for the motion sensor that turns on the light to work on time, it must be installed correctly. Here are some tips to follow:

Connection diagrams

To connect the motion sensor to the network and the lamp, you must first understand the installation diagram. Otherwise, you can get confused, because the device has 3 contacts: zero, input and output to the lighting device.

Figure 1 - connection without a switch, Figure 2 - connection with a switch extinguishing the light, Figure 3 - connection with a switch giving light

When connecting a motion sensor to a lighting system, you can go in three ways:

• Connect the device to the electrical network without a switch, if you need to make the sensor entirely responsible for turning the light on and off, which makes sense if it is necessary to illuminate local area or swimming pool.
• Together with a device that captures air vibrations, use a switch in the room that forcibly extinguishes the light in the room, which means that the lamp must be connected to electrical network bypassing the motion sensor.
• Supplement the power supply circuit of the lighting system not only with a device that automatically supplies light, but also with a switch, when pressed, the light will go out and will not come on due to movements made in sleep.

Instructions for connecting a motion sensor to control lighting

Feeding device electricity into the lighting device only after detecting movement, it will work if you install it as follows:

Sometimes a motion sensor needs to be connected together with a switch. This task must be performed so that the switch is connected to both the lighting fixture and the motion sensor. This can be done as follows:

1. Find the wire that runs from the lamp to the switch.
2. Connect another wire to the detected wire, directed to the red contact of the motion sensor.
3. Take the wire from the other side of the switch and insert it into the contact Brown device that automatically turns on the light.
4. Route the wire belonging to the lamp to the motion sensor terminal.

Video: how to connect the device

Video about installation of the device

Solving possible errors

When installing a device that turns on the light after detecting human movements, you can make the mistake of creating a bad contact at the neutral wire. This happens if the wire is inserted into the terminal together with construction debris or is not pressed, which leads to the formation of a dense layer of carbon deposits, significant heating, oxidation and loss of contact. If the sensor does not work, then the wires need to be checked and, if necessary, cleaned or compressed.

Sensor malfunction may be a consequence of deformation and breakage of the aluminum core. To see if this is true, you need to use a voltmeter - bring its probes closer to the terminals. True, the device may not operate even if the device detects voltage. In such a situation, you should replace the old lamp with a new one, because, most likely, the problem lies in the burnout of the channel filament in the lighting device.

Sometimes people who have installed a motion sensor in a room encounter the following problem: the lights will not turn off, despite the fact that the device that responds to human movement is working properly. To deal with this problem in the operation of the device, you need to check the time period. Probably, this value is too large and does not allow the output contact responsible for the operation of the lamp to open. In this case, it is necessary to slightly reduce the response time delay.

Adjusting the motion sensor to turn on/off the light

The first thing you need to do is set the time on the device. The sensor allows you to select an interval from a second to 10 minutes. It will be easier to decide over time if you listen to the following tips:

• the optimal period for supplying light to the stairs is a few minutes, because they rarely stay longer in such a place;
• normal period of time for supplying light to utility room- 10–15 minutes, because you often have to take something from such a room.

The sensor is supposed to set a response delay after detecting the movement of an object. This value can range from a few seconds to 10 minutes and is determined by how fast the person moves. For example, a corridor is crossed quickly, so it is better to mount a sensor with a shortened “Time” parameter in it.

Without configuration, the device will not work correctly

The illumination level, dependent on the “Lux” regulator, should be adjusted so that the sensor performs its task at times when the room is illuminated less than usual. It is recommended to equip a room where a lot of light enters from the windows with a motion sensor with a “Lux” regulator set to the initial or middle position.

The sensitivity of the device, which triggers certain actions in response to human movement, is controlled by the “Sens” regulator. This value is influenced by the distance of the device from the moving object and the weight of the person who made the sensor work. Therefore, if the light sensor turns on for no reason, it is necessary to make the sensor less sensitive. And it’s worth thinking about increasing the device’s response rate only if there is no action from the sensor while a person is passing by it.

The motion sensor has a complex design that must be adjusted to special operating conditions. Ignoring the rules risks the fact that the device will work contrary to the wishes of the owner of the premises.

A motion sensor for turning on a light is a device capable of detecting the movements of a person or other living objects and, accordingly, controlling the lighting.

Using special sensors (thermal, sound, etc.), it detects changes in space and turns on, turns off or adjusts the level of lighting. A presence sensor for turning on lights that reacts to heat may not even “notice” a person walking past in winter if the latter is dressed very warmly. Nevertheless, it can easily capture any living creature in warm time of the year.

How it works?

The operating principle of the motion sensor to turn on the light is to use a sensor (pyroelectric device). It operates very accurately by increasing the output voltage, subject to an increase in the level of IR radiation compared to the general background. The light is turned on using the sensor's internal relay.

Regardless of the type of device, the output signals that the presence sensor receives to turn on the light, depending on the need, go directly to the controller, which issues control signals to the control point:

• alarm;
• relay for turning on the light;
• ventilation system;
• room air conditioning system.

It helps " smart home"be extremely useful to the owners.

For example, while you open the door, the house has already begun to ventilate the room, filling it fresh air. Or, on the contrary, it starts airing or cooling when there is no one in the room.

Types of motion sensors

On modern market You can find many devices that one way or another detect the presence of someone in the house or on the street. General concept"motion sensor for turning on the light" can be divided into 4 types, depending on the main sensor element:

• IR sensor for turning on the light (infrared).
• Ultrasound sensor (ultrasonic).
• Microwave sensors (microwave).
• Combined.

In addition, there is a sound sensor to turn on the light and a cotton sensor.

Each of them is installed in a specific place and performs its functions best when installed correctly and rationally.

IR sensor

The infrared light sensor for turning on the light detects changes in the thermal radiation of living beings or other objects (such as a car) using several lenses that act as indicators.

Advantages:

• Increased accuracy.
• Wide temperature range of use.
• Harmless to pets.

Flaws:

• Excessive sensitivity to household appliances(batteries, air conditioners).
• Reaction to sunlight.
• Lack of fixation of objects coated with radiation-impermeable materials.

Purpose of the infrared motion sensor

The main tasks of infrared sensors are:

• Energy saving. The light will only turn on if it is really needed.
• The effect of presence. When you install the sensor on the street in front of the gate on the site, in the entrance, on the windows of the lower floors, when it is triggered, you get the feeling that someone is at home. This, on the one hand, causes a feeling of comfort, and on the other, scares away robbers and bandits.

Despite all its usefulness, it happens that this light sensor for turning on the light gets on people’s nerves. Not everyone likes its ability to soothe and take care of the lights not turned off.

You can often hear: “Why is it clicking there?”, “Do I now have to move all the time for the light to be on?”, “What if I don’t want it to be on?”

There is only one answer to all these questions, and it is quite simple: when installing the sensor, you only need to use several additional switches that will ideally suit the requirements of the residents and create the possibility of comfortable operation of the system.

The circuit diagram for connecting the sensor to turn on the light will be described a little later in this article.

Ultrasound sensors

Measuring the surrounding space using sound waves is the prerogative of ultrasonic sensors. They generate sound waves that are reflected from objects with any movement. The frequency of these reflections is continuously measured, and a kind of echo sounder is obtained. The signal is sent to the sensor receiver and gives a command to turn the lighting on or off.

Such sensors are most often used in the automotive industry to create parking sensor systems.

Advantages:

• Possibility of installation over large areas.
• Insensitive to weather conditions.
• Resistant to dirt and dust.
• Comparability with different materials housings.
• The widest possible temperature range for operation.

Flaws:

• Sensitivity of pets to ultrasound.
• At long-term use may cause headaches.

Microwave sensors

The microwave darkness sensor for turning on the light works by emitting high-frequency electromagnetic waves, which, when they hit an object, are reflected, and the quality of these reflections is recorded by the sensor. Any changes in the signal trigger the program installed by the owner.

Advantages:

• Ability to detect objects behind obstacles.
• Resistance to aggressive environment.

Flaws:

• Not safe for the human body.

Can only be installed where traffic is minimal.

Combined sensors

Combined light sensors for turning on light imply a symbiosis of several object detection technologies.

Advantages:

• Possibility of the most accurate work.
• Full control of the area required for surveillance.
• Wide range of individual settings.

Flaws:

• Installation can only be carried out by a specialist.
• If one of the systems fails, a complete reconfiguration will be required.

Cotton sensors

Many have seen such a device in films, but not everyone was lucky enough to experience it personally. How great it is: you went to bed, but forgot to turn off the light. The warm bed doesn't want to let go. The solution is clap, and the light is turned off. Do you urgently need to turn on the light? Clap - and the room is illuminated again.

Remote control of the light is undoubtedly very convenient. But do not confuse a cotton switch with an acoustic switch (we will discuss it below).

Such a device works differently than a light sensor to turn on a light.

With its help you can adjust not only the lighting, but also:

• ventilation;
• transformers;
• any electrical equipment.

Important! Be sure to comply with load power limits.

Algorithm of actions:

• The first clap means the voltage is turned on.
• Second clap - shutdown.

Very simple, you will agree.

The cotton sensor is a kind of noise sensor for turning on the light. This means that its installation is advisable only in those rooms where the stationary noise level is not too high. And certainly not where the holiday is planned. The applause of guests can create a real disco light and music.

Ideal room:

• utility room;
• basement;
• pantry;
• bedroom;
• children's room.

Where you should not install a cotton sensor:

• crowded rooms;
• offices;
• production rooms;
• workshops, etc.

It is highly recommended to install such equipment in a children's room. This is not only convenient, but also provides additional safety for your child. Conventional switches are quite high, and children have to either climb up or ask their parents for help. The incidence of chair falls in this situation is impressive and the injury rate is very high. Cotton is a good alternative.

This is also useful for people with disabilities.

Acoustic sensors

The difference between this type of switch and the previous one is insignificant, but it is there. The acoustic sensor reacts to absolutely any sound exceeding a specified threshold in decibels. Its installation is advisable in entrances to save energy.

As soon as the door slams, footsteps are heard, the lights turn on, and then turn off a few seconds after everything has gone quiet. An important difference: cotton reacts only to claps!

Motion sensor settings

Of course, each automatic light switch sensor has its own parameters, but in general there are certain performance standards:

• Voltage - 220-240 V and 50 Hz.
• Delay timer (on time) - 2-8 seconds.
• The voltage supply time is set using the regulator.
• Sensitivity to light - 2-1000 Lux. Installed on the switch. The minimum number of modes is 2 on the simplest models. To make it clearer: 100 Lux means that the sensor will only operate in dark time days. On maximum settings The sensor's operating capabilities are not limited by the degree of illumination.
• Viewing distance is up to 15 meters. When combined different types sensors this parameter can be increased.
• Response speed is 0.5-1.5 milliseconds. If the object moves slowly and its temperature (clothing) merges with the general thermal background, the sensors do not work. Moving too quickly also causes detection difficulties.
• Maximum current - may vary depending on the area in which the sensor will be used, from the required minimum up to 1500 W. The load power is determined by an electromagnetic relay.
• Viewing angle - 360 degrees for ceiling sensors. For wall-mounted ones - from 100 (for corners) to 180 (for a straight wall). Height becomes a decisive factor in viewing capabilities: the higher, the more.

IR sensor circuits

The volume sensor for turning on the light is not as difficult to install as it might seem at first glance. A minimum knowledge of electromechanics is sufficient.

For example, we use the Chinese LX-01 sensor and connect it to a regular incandescent lamp.

Connection diagram for the light sensor (action algorithm):

• Select the sensor model you like.
• Determine the installation location.
• Consider the layout of the room (windows, doors, patterns of movement of people, tall furniture).

Important! If there are no windows in the room, then this is an advantage, because the sensor does not have to be additionally adjusted to the degree of illumination - the room is always dark. If the room has doors on each wall, the sensor of the selected type will have to be mounted in the corner, since it has a viewing angle of 120 degrees.

• Study the network connection diagram, which is always included with the instructions.
• Do not connect the sensor differently, do not confuse the wires, otherwise you will hear a pop when turned on and the device will be permanently damaged.
• If necessary, add a control switch to the circuit so that you can adjust the lighting manually.
• Test all wires before connecting the device to the network using a tester.
• Connect the wire coming from the switch to the lamp to the red contact of the sensor.
• The wire on the other side of the switch is to the brown contact.
• To the blue contact is a wire that does not approach the lighting fixture from the side of the light bulb.

Important! Be sure to follow all safety precautions when working with electricity:

• Wear thick rubber gloves.
• Turn off the electricity in the apartment.
• Upon completion of work, insulate exposed wires.

All that remains is to hang the sensor on the wall and check its functionality! To do this, leave the room and close the doors behind you.

Enter the room. The first time the motion sensor turns on the light, it sometimes takes a while to respond. It's okay, you'll be able to adjust the settings later using the controller.

If you installed a cotton or acoustic sensor, make the appropriate sound. Enjoy using it!
