RCWL-0516 Microwave Radar Motion Sensor Arduino

Microwave radar module capable of detecting movement by sending microwaves and detecting reflection changes.

The radar operates at a frequency of around 3.15 GHz and needs a voltage of 4V to 28V. After detecting motion, the module sets the output level to high 3V3.

Specification:

- Working voltage: 4V-28V DC

- Working current: 2.8mA

- Distance detection: 5m - 7m

- Superstructure power: 20mW

- Output Signal: TTL (High 3.3V, Low 0V)

PIN OUT:

- 3V3: Support 3.3V output voltage, driving current is 100mA

- GND: Ground

- OUT: Control the output signal, when it detects an object, output will be high (3.3V), otherwise low (0V)

- VIN: power input (4V-28V)

- CDS: Streaming trigger signal: less than 0.7V, Low output level (OUT), Over 0.7V it works normally.
