This device can pick up invisible infrared emissions from any heat source without emitting any radiation. The detector activates the output of the circuit when a heat source moves in front of the switch and turns off once it stops picking up motion, after an adjustable delay time.
It turns out to be extremely useful for driving the automatic turn-on or turn-off of our LED products. To better suit your needs, you can adjust the delay time between 5 sec, 30 sec, 1 min, 3 min, 5 min and 8 min.
