Features:
The RCWL-0516 is a doppler radar micro wave motion sensor module which can act as an alternative to a PIR motion sensor. Instead of sensing changes in infra red radio emitted by a moving person this sensor uses a microwave Doppler radar to detect moving objects. It has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before returning to its idle LOW state. This Device can sense motion through objects Eg. roof, cupboard, Wall, etc.
Board Layout:
3V3 - Regulated output (reference only)
GND - Ground / 0V supply input
OUT - Trigger: HIGH (3.3V) motion detected / LOW (0V) idle
VIN - 5V-12V supply input
CDS - Sensor disable input (pull low to disable)
