Mini doppler radar sensor module with wide DC operating voltage 4-28V.
This mini radar motion sensor module is equipped with RCWL-9196 chip based on the doppler microwave induction technology.
It will comtinuously output a high level TTL signal when there is motion. 360 degree sense area, no blind angle detection with a maximum 7m sensing distance alsdo with adjustable delay time and sensitivity. It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.
Notice:
1.The right side of the induction module should't be near any metal.
2.The front/back side should a minimum of 1cm space

Adjustment Part Introduction:
1.C-TM Adjust repeat trigger time,default trigger time is 2s;increasing capacitor's capacity will make repeat trigger time longer;and actual counting trigger time can operate as below: Stick capacitor on C-TM,test 9196 3-pin frequency F,repeat trigger time T=(1/f)*32768
2.R-GN Detection distance adjustment;connect with resistor and detection distance will become shorter;if not connect,detection distance is 7m;if connect with 1M ohm resistor,detection distance is 5m
3.R-CDS Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (that is 196 9-pin) by R-CDS ,CDS connects with photoresistor,you can close detection function at night
Pin Definition:
3V3:3V3 power output
GND:ground
OUT:control output;when detect moving objects,it will output high level
VIN:input voltage,4-28V
CDS:enable control chip,lower than 0.7V,OUT will output low level all the time
