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
