Microwave Radar Sensor RCWL-0516
Sensors that employ electromagnetic waves with frequencies in the range of 0.3–40 GHz (wavelengths from 1 mm to 1 m)
RCWL-0516 Microwave Radar Sensor uses a “Microwave Doppler Radar” detect Moving Objects, Sensitivity Range of ~2 meters Human Body Sensor.
Range of microwave sensor can be increased by doing suitable modification in Circuit.
The board has the option to attach a cadmium disulphide ("CDS" on the board) light dependent resistor to disable the output when it is light, for when the board is used to control lighting.
