Adjustable distance, high sensitivity, the module has a far sensing distance, reliable, large induction angle and has a wide supply voltage range

Widely used in a variety of human induction lighting and burglar alarm and so on.

Adjustment part introduction:

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.

R-GN:
Probe distance adjustment;connect with resistor and probe distance will become shorter; if not connect, probe distance is 7m; if connect with 1M ohm resistor, probe distance is 5m.

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 probe function at night.

Pin definition:

3V3: 3V3 power output

GND: ground

OUT: control output; when probe 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
