Ultrasonic Movement Detector II Kit

$17.95

Ultrasonic Movement Detector II Kit – K49.  Soldering required.

This is similar to our CK203, however the re-design has allowed better stability and sensitivity control. The circuit uses a matched pair of 40 kHz transducer elements to detect movement up to 22 feet away. You may add a relay (not included) to switch higher voltage loads.
