RCWL-0516 Microwave Radar Sensor Module Human Body Switch Induction Module

Description

The RCWL-0516 Microwave Radar Sensor module can be used as an alternative to the common PIR motion sensor. It is widely used in burglar alarms and security lights. unlike the PIR sensor, this sensor instead of sniffing the blackbody radiation from a moving person, it uses a “microwave Doppler radar” technique to detect moving objects. It has a detection range of 5~9 meters. When triggered, its TTL-level output (OUT) pin will switch from LOW (0 V) to HIGH (3.3 V) for a finite time (2 to 3 s) before returning to its idle (LOW) state.
