Adjusting Piece Introduction

1 - C-TM

Set the repeat trigger time, the default trigger time is 2 seconds; Increasing the capacitor capacity will increase the re-trigger time, and the actual counting trigger time can work as follows:

Bar capacitor in C-TM, test 9196 3-pin frequency F, repeat trigger time T = (1 / f) * 32768

2 - R-GN

The detection distance adjustment, connect with the resistance, and the detection distance will be shorter; detection distance 7m if not connected; If connected with 1M ohm resistor, the sensing distance is 5m

3 - R-CDS

Internal VCC parallel connects to CDS pin (196 9-pin) with internal 1M ohm resistor via R-CDS; Connected with CDS photoresistor, you can turn off detection function at night

Pin Definition:

1. 3V3: 3V3 power output
2. GND: ground
3. OUT: control output, high level output when detecting moving objects
4. VIN: input voltage, 4-28V
5. CDS: enable control chip, lower than 0.7V, OUT always output low level

Note:

1. No metal should be placed directly in front of the induction side
2. Front / back side should leave more than 1 cm gap
3. Module and installation carrier
