Today, few people can be surprised by the various innovations used in the arrangement of residential premises. It has been practiced for quite a long time to use such a device, which is responsible for turning the lighting on and off when a person appears in the room. Despite the apparent complexity of such equipment, almost everyone can make it on their own, for this you just need to know all the nuances of this work and carefully follow all the installation recommendations.
Therefore, it is necessary to consider in more detail how to properly install and connect a motion sensor for lighting, as well as deal with the design features of such a device.
Scope of application of motion sensors
If earlier this device could only be purchased for a lot of money, today almost everyone can afford to have such equipment at home.
It is usually installed in the entrances of residential buildings, in private buildings, as well as in various enterprises, which provides people with additional comfort and safety.
The main purpose of the motion sensor is to turn on the lightingdevice when a person appears. In this case, the automation is activated, which is responsible for activating the entire system. Moreover, such a mechanism can be responsible not only for turning on the light, but also for sound, alarms, etc. But then we will talk about exactly how to connect the motion sensor to the light bulb. This is due primarily to the fact that this version of the device is the most widespread among the population.
Technical design features
Externally, the motion sensor for lighting has the form of a small plastic box, which has a rectangular or round shape. The device is also equipped with a small diameter hole covered with a matte film. This plastic partition is called a Fresnel lens, and it is on its properties that the principle of operation of the sensor is based. It must be handled very carefully so as not to damage its integrity and not disrupt the operation of the entire system.
Motion tracking is also possible thanks to the infrared beam beam inside. In addition, the case is also equipped with special hinged legs, thanks to which you can change the position of the device.
The sensor can be fixed both on the wall and with the help of a special auxiliary bracket. Sometimes there may be an on/off button on the case, but there are samples without it, it all depends on the specific model and type of equipment used.
Types of motion sensors for lighting
To figure out how to install a motion sensor, you must not only study the information on its installation, but also select the desired sample, since there are several categories of such equipment. So, there is a division of these mechanisms in accordance with the place of installation and according to the type of signaling device, but the two largest groups are sensors for the street, or outdoor, and for the room (internal).
The principle of operation of samples for the street is based on the calculation of the distance from the device to the object. This option will be convenient for private houses with a large territory, as well as massive administrative and economic structures. Some models require a spotlight to work well, which is important to consider when installing.
The room sensor can be connected in any of the rooms, however, when using it, it is important to ensure that the microclimate is more or less stable, that is, without sudden temperature changes, otherwise the device may simply fail.
In addition, this equipment can be divided into the following categories:
- Ultrasonic motion sensors for lighting. They function by reflecting ultrasound from surrounding objects. This option is affordable, durable and easy to use.
- Infrared devices. The principle of their operation is based on sensitivity to temperature changes. This means that when waves with a certain heat index enter the radius of its coverage, the light turns on automatically, and you can always set the desired parameter so that the mechanism does nottriggered, for example, when an animal appeared.
- Microwave sensor, identical in its operation to a standard locator. Signals having a certain frequency are periodically transmitted to the device, as a result of which, after capturing them, the device turns on. Such samples have some similarities with ultrasonic devices, but their cost is higher.
Pros and cons of equipment
In order to understand how to properly connect a motion sensor to control the light, of course, you need to study all the positive and negative sides of such a device. And based on this data, draw a conclusion whether it is worth installing it or not.
The advantages of this popular and convenient mechanism include the following:
- Low power consumption. Thanks to this sensor, you can not be afraid to forget about the need to turn off the light under any circumstances, since such a problem is solved automatically.
- User comfort. The use of this equipment will avoid long searches for the switch in the dark.
- High level of functionality. These devices are quite capable of doing without wires, which makes their use more convenient.
However, such equipment has two main disadvantages:
- High price, as a result of which not everyone can afford its installation.
- Relatively complicated installation process. The most important elements in deciding how to connect a motion sensor are instructions and a diagram. Mountingrequires the presence of certain skills in working with such equipment, otherwise it would be more correct to seek help from specialists.
How to determine the place to mount the device?
Before you connect the motion sensor to the light bulb, you need to carefully choose the place of its installation, which must be calculated so that the device always works and does not react to extraneous actions. It is necessary to protect the mechanism from external interference and ensure its normal operation both from the mains and stationary.
Here it is extremely important to remember that the sensor must not be mounted near pipeline central heating radiators, near air conditioners and electromagnetic devices.
If the equipment is connected in the wrong place, it can react even to slight vibrations, such as swaying trees or movement outside the perimeter of the house. Therefore, it is necessary to choose a suitable area where the device will not be subjected to any thermal or other effects, and within its coverage area there will be no foreign objects that could affect its operation.
Setting the motion sensor for lighting
Any technical equipment used in everyday life, as you know, requires pre-configuration. Therefore, if a question arises regarding how to install a motion sensor, it is initially necessary to adjust its mechanism so that it works as accurately as possible.
Usually connectionthese devices are connected directly to the mains electricity with a standard voltage of 220 V. This should not be done only in the case of radio models, which are based on the use of a battery.
In order to make it easier for the master to connect a motion sensor, the installation diagram is usually displayed directly on the surface of the device in the area of the terminal block.
So, you can test whether the equipment is functioning by paying attention to its indicator. If it is lit, then there is nothing to worry about, but if not, then you should configure the device differently. As a rule, not only the blinking itself plays a certain role, but also its frequency, which increases when a person appears in the zone of its radius of action.
The case of any of the devices is usually equipped with special adjustment knobs, thanks to which it is much easier to set up the work so that electricity is consumed in the minimum amount during the day, it becomes possible to adjust the coverage range of the sensor, etc.
Tools for self-assembly of the motion sensor
Such a device, if desired, can be designed with your own hands. This will require the following set of tools:
- one-piece body (an old camera base will do);
- element-type control base (available from specialized stores);
- screws;
- wires;
- soldering machine;
- screwdriver.
Further all functionalparts of the future sensor need to be assembled, while many owners have the question: "What is the optimal connection scheme for the motion sensor?" In order for the design and connection of the device to pass without unnecessary problems, it is necessary to take into account the features of the device, its technical characteristics and, of course, the correct connection algorithm. Therefore, you should understand in more detail what these installation instructions are.
Device installation diagram
When performing such a procedure as connecting a motion sensor, the circuit involves pulling three wires from the distributor box to the device - this is phase, zero and the third contact from the twisting of the switch with the lamp. In this case, it becomes possible to short-circuit the mechanism so that the light turns on forcibly and for a long time, even in the absence of movement. This will be convenient, for example, when working in a garage, when very little movement is made when repairing a car. This can be achieved even despite the fact that almost all devices of this type are equipped with the ability to control the duration of the lamp after a signal is received about the movement that has occurred in the sensor coverage area. As a rule, the terminal block of the device has several designations, the main of which are L (phase), A (lamp), N (zero).
Motion sensor connection for lighting
When solving the problem of how to connect a motion sensor to a light bulb, you should take into account the following installation rules.
The device is connected in a chain between the lamp and the switch by installing two wires that disconnect both of these parts from each other. This means that the device will be located between them. As a result, the lighting element will function both from the sensor and from the switch.
It also happens that it becomes necessary to mount several similar mechanisms in a row, for example, in a warehouse. The scheme of their device is similar, but in this case the wires must be placed around each of the lamps separately. Alternatively, the main wire can go in a circle from the switch, while the lamps will be connected to it in a chain. In this case, the sensors are mounted both between the input wires and at the output of each light bulb.
To make the installation as safe as possible, the room must first be de-energized, the wiring must be cut in those places where the sensor wires will be connected, which, in turn, must be stripped and twisted together. At the end of the work, it is important not to forget to carefully wrap each of them with electrical tape.
Recommendations for mounting motion sensors
It is important to remember that the installation of any of these devices requires an individual approach, since the connection instructions may be different, but the main thing here is to equip the device in a place where extraneous signals will not affect its operation.
When reasoning ontopic: "How to connect a motion sensor (light on) yourself", you should take into account the following tips:
- For mechanisms with wires, the installation site should be carefully selected, since such devices should not be often transferred from one place to another.
- It would be more correct to mount an additional switch, while both devices can function separately from each other. This will allow you to dim the light in the standard way.
- Designed rooms are best equipped with a built-in alarm that will fit perfectly into the interior.
- Before purchasing a sensor, you should seek help from a consultant with a question about what range the device should have in a particular room. A good solution would be to connect a ceiling mechanism that is almost invisible to the eye.
- It is important to prevent the device from being exposed to direct sunlight, otherwise the device may fail soon.
Following all these recommendations, it will be possible to save yourself from many difficulties. That's all. Now you know how to connect a motion sensor to a light bulb. And this knowledge will help you correctly install and ensure that the equipment performs well for a long time.
