RCWL-0516 Microwave Radar Sensor
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. Like the PIR sensor, 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 ~7 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. This flexible sensor module can easily be used in conjunction with many microcontrollers and even without a microcontroller at all. It can handle power supply inputs anywhere from 4 to 28 V.
Pinouts:
- CDS – Sensor disable input (low = disable)
- VIN – 4- to 28-V DC supply input
- OUT – HIGH (3.3 V) motion detected/LOW (0 V) idle
- GND – Ground/0 V
- 3V3 – Regulated DC output (100 mA max)
