How to connect a motion sensor?
Motion sensors are mainly used forprotection of industrial facilities from intruders. Also, motion sensors are widely used in everyday life to connect many lighting devices. Let's look at how to connect a motion sensor at home for more useful purposes. Goals are always there.
Many with the help of the motion sensor, decidedthe problem of switching on and off the lightening of the courtyard and the staircase (private house). Earlier, when the light was turned on at the bottom of the ladder march, it was necessary to go back to turn it off after turning on the upper switch. Now that the sensor has been installed, the light automatically turns on as soon as someone approaches the ladder, both from below and from above. Very comfortably. The sensor also automatically turns off after a certain time. The work timer can be adjusted. Before you correctly connect the motion sensor, you need to figure out what they are.
Types of sensors
Motion sensors are wall and ceiling. Wall - the radius of capture of 180 degrees, ceiling - the radius of capture of 360 degrees. You can select a sensor for the intended installation location, internal or external. Also, the sensors are divided into adjustable and unregulated. The adjustable sensor has the functions of regulating the level of movement, adjusting the period of operation of the instrument sensor, the function of adjusting the work depending on the time of day. You can also choose a sensor by its color, shape, size and, of course, by price and cost. The cost of motion sensors depends on the characteristics and brand. But do not assume that they can not afford it. a normal motion sensor costs around ten dollars, but there are also cheaper. For example, a light bulb with the function of automatic on / off will cost one and a half to two times more expensive.
Now about the installation. As mentioned before, the motion sensor can be installed on a wall, or on the ceiling of a room. You can also connect a searchlight with a motion sensor. Comes with dowels for installation with instructions for installation and connections. You can also figure out where to install it.
Connecting the sensor to the lighting device
Connect the motion sensor to the monitoredthe device (luminaire) and the network will be a simple procedure if you carefully study the connection scheme. The connection diagram is drawn in the language of electricians. We translate this into a more understandable language. There are four contacts on the sensor pad of the motion sensor. Below are the symbols and their description:
- L - postings from the network.
- N - the second post from the network and here one wire from the lamp.
- A - the second post from the lamp.
- _ - Earthing.
Everything, motion sensor with a lamp installedand connected to the network. You can now proceed to the test. When everything is tested and adjusted, you will have an excellent system of automatic lighting on / off.
