Setting Part Input
1 - C-TM
Set repeat trigger time, default trigger time 2 is seconds; Increasing the capacitor capacity will extend the repeat 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
Detection distance adjustment, connect with resistor and the detection distance will be shorter; If not connected, detection distance is 7m; If connected with 1M ohm resistor, detection distance is 5m
3 - R-CDS
Internal VCC parallel to CDS pin (196 9-pin) with internal 1M ohm resistor Binds with R-CDS; CDS connects with photoresistor, you can turn off the detection function at night
Pin Description:
- 3V3: 3V3 power output
- GND: ground
- OUT: control output output high when detecting moving objects
- VIN: input voltage, 4 -28V
- CDS: enable control chip, lower than 0.7V, OUT always output low level
Note:
- Any metal immediately in front of the induction side should not be placed
- Front/back side should leave more than 1cm space
