If you are interested in the question of how to connect the motion sensor correctly, then you have opened the necessary article. Having studied the material below, you will understand that the connection is almost the same as installing a conventional switch, and the main difference between them is the principle of operation - mechanical and automatic.
Just a few recommendations
At the beginning of the article I would like to give you some tips and tell you what to avoid when connecting the motion sensor:
- First, any obstacle in the sensor's field of view can affect its false triggering,which leads to unnecessary switching on of the lighting( we are talking about trees, bushes, etc.)
- All sources of heat and electromagnetic radiation can interfere with proper operation( do not install the sensor in front of other devicesin, emitting light)
- It works at a certain angle and will only fire in the direction in which the
- is installed. Try to keep the motion sensor clean, because dirt on it can lead to poor performance or a reduced radius
- The motion sensor for lighting is not designedfor work at high loads, since the average power of this usually ranges from 500 to 1000 W, so select the lighting equipment by the power of the
Connecting one motion sensor to the
circuit First, you will learn how to connect one motion sensor to the circuit. It has three terminal clamps. From one terminal, the wire is directly connected to the phase, the other terminal is for the neutral wire, and the third is for connecting the lighting device. As you can see, the connection diagram of the motion sensor is quite simple.
If you would like the lighting to work continuously even when there is no movement in the visibility zone, you must connect the switch directly to the motion sensor in parallel. To do this, the switch is connected from phase to part of the wire located between the motion sensor and the lighting device. When the switch is open, the motion sensor will operate as required, but if the switch is closed, the lamp will bypass the sensor. Everything is simple enough.
Connecting several sensors to the
circuit Now, let's try to explain how to connect the motion sensors, if there are two or more of them. And this is required if the radius of action of such a sensor is too small and it is not enough to cover the necessary territory.
It is necessary to select the place for mounting the sensor so that it opens the largest viewing angle. But in the premises of chaotic planning, it is almost impossible to do this with a single device. In this case, the sensors are connected in parallel to one phase! If you connect the sensors to different phases, be prepared for a short circuit due to interfacial connection.
Mounting position
Even if you found a motion sensor circuit for lighting, choosing the best place to install is not so easy. You must take into account several factors that affect the quality of its work. So, do not install it near heating systems, air conditioners, sources of electromagnetic radiation( microwave oven, radios, televisions).
Before choosing the location, you need to determine how the traffic sensor for the lighting will be connected to the network. Motion sensors operate either from the mains voltage of 220V or from the battery. More common are traffic sensors operating from a central network. They can be connected either through the box, or by using wires coming from the chandelier.
The second option is more acceptable in view of the fact that often the boxes are hidden under the wallpaper and even if you find them, then it is very difficult to understand which wires you need without professional skills and knowledge. Therefore, and connect the motion sensor we advise from the wires going to the chandelier.
In practice,
Let's say you need to connect a motion sensor for lighting in the bathroom. Surely you have one luminary there and it is located on the wall. The motion sensor for lighting is best placed below it.
On the other hand, if the motion sensor is located on the street or in a room where there is enough sunlight in the daytime, care should be taken to configure the sensor. There are several controllers on the sensor that can be adjusted: response time, light level, noise level and sensitivity( allows you to set the range).Adjust the sensor so that it does not work under strong light.
In practice, the connection of the motion sensor should begin with its inspection. On the box( usually under the terminals) is the connection circuit of the motion sensor. Terminal three and they have the following designations: L, N and L with an arrow. The conventional L stands for the terminal to which the phase is connected. N is the zero wire, and L with the arrow is the wire for connecting with the lamp.
Note the wires coming from the wall to the chandelier. There are two. Strip the wires and connect the terminal block of three pieces. The scheme of the motion sensor for lighting is simple: through the upper terminal of the chandelier pad, draw a phase and close it at the sensor terminal marked with the letter L. Through the middle terminal of the chandelier pad, draw a zero wire and close it at the sensor terminal with the designation N.
The middle terminal of the chandeliertwo more wires. One wire connects to the chandelier, and the other - to the second outlet. The phase wire from the sensor terminal goes to the other terminal not directly, but through an open relay. The terminal with the letter L and the arrow on the motion sensor is connected to the third terminal of the chandelier pad. To the bottom terminal the chandelier pads connect a light bulb and an additional outlet. The relay will operate when the motion sensor detects any fluctuations. As you can see, the connection of the motion sensor for lighting is not difficult.
