Motion sensor, we also can say occupancy sensor, which is used in corridor, staircase or other dim places for electric lighting control. If there is motion being detected, it is assumed that the place is not empty, and thus needs to be lit. When there is no motion, the light will go out automatically after preset delay time. Light turning off to some extent can save substantial amounts of energy. We will try to control 2 led lamps with 2 infrared movement detectors (W-01) and AC activated receiver with time delay function (S2DA-AC220). The working distance of wireless signal is 100m (open field). The detection distance of motion detector is 10m. The RF receiver is an adjustable time delay receiver. This delay time is user-selectable. Delay time can be adjusted as you like within 0 second~99 hours.
Note: Don’t install 2 infrared motion detectors within a small space because of generation of interference.
Let’s see the following material. We have 2 motion detectors, receiver, 2 AC lamps, AC 220 power supply.
The wiring and operation pictures are as follows:
Wire 2 lamps to the rf receiver.
Set delay time: 5 seconds for each relay and switch on the power.
Hand moves around the first motion detector, lamp 1 turns on automatically.
When there is no motion, lamp 1 will be off by itself after 5 seconds.
Hand moves around the second motion detector, lamp 2 turns on automatically.
When there is no motion, lamp 2 will be off by itself after 5 seconds.
