Crystal-lock Ultrasonic Motion Detector
(DC 12V)
A pair of 40 KHz ultrasonic transducers detects moving
objects or human bodies up to 10 meters. When an object is moving in front of the
transducers, the detector responds by energizing the relay (LED on)
for about 2 seconds. This will repeat continuously until the object
stops moving. The transducers are mounted off
board via 2 pairs of cables (as shown in the picture )
Plastic enclosure provided for the main board
Applications : Add-on motion detector for existing security alarm system, proximity switch, visitor chime (when used with door chime), . .
