The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights

 this sensor also detects only movements within its detection range

But instead of sniffing the blackbody radiation from a moving person, this sensor uses a “microwave Doppler radar” technique to detect moving objects. It has a sensitivity range of ~1 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

Features :

1. Transmission signal processing control chip RCWL-9196
2. Wide operating voltage range from 4.0V to 28.0V
3. Penetrating detection capability, compared with the traditional infrared feeling PIR
4. Adjustable Block time and distance

   Package Includes :

   1 x RCWL-0516 Microwave Radar Sensor

5. 3.3V output power supply
