Instructions

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
