A Doppler radar microwave motion sensor module using the RCWL-9196 IC replacing a PIR motion sensor such as the HC-SR501/HY-SRF05.
equipped with an RCWL-9196 chip. When triggered output pin switch from (LOW) 0V to high (3.3V) for 2 to 3 seconds before returning to its LOW state.Maximum 7 meter detection distance with adjustable delay time and sensitivity. The detector operate through glass and other obstructions, providing better performance than traditional infrared (PIR) detectors. DIY microwave motion sensor light switch, security systems, human sensor toys, etc.
The component side of the board should face detection area for maximum sensitivity, however, it will also detect from the back side at lower sensitivity. No metal objects within 1cm of the antenna.

Pin Definition
3V3: 3.3V power output, can be used as a reference voltage or as a low current(less than 100mA) 3.3V power supply.
GND: Ground
OUT: Control output;when a moving object is detected,it will output high level 3.3V
VIN: 4-28V Input voltage
CDS: CDS photodetector output.
Pad/ Function
C-TM: Regulates the repeat trigger time. The default (unpopulated) time is 2s. An SMD capacitor mounted here will extend the repeat trigger time. Pin 3 of the IC emits a frequency (f), and the trigger time in seconds is given by (1/f) * 32678
R-GN: The default detection range is 7m, adding a 1M resistor reduces it to 5m.
R-CDS: Internal VCC parallel connection with internal 1M Ohm resistor to CDS pin (RCWL-9196 pin 9) through R-CDS.
Package Includes:
5 pcs Microwave Doppler Radar Motion Detector Sensor RCWL-0516 Module Board
