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:
1.3V3:3V3 power output
2.GND:ground
3.OUT:control output;when detect moving objects,it will output high level
4.VIN:input voltage,4-28V
5.CDS:enable control chip,lower than 0.7V,OUT will output low level all the time
