About pin header:
CDS = No connection
VIN = 5vdc (+) (9v battery also Ok)
OUT = 3.3vdc signal out when triggered
GND = 0vdc (-)
3V3 = No connection (in most applications)

About Adjustment Part:
C-TM: Adjust repeat trigger time (default 2 s). Adding a capacitor will give a longer repeat trigger time.
R-GN: Detection distance adjustment (default 7 m). Adding a resistor the detection distance will become shorter. If connected with a 1-MΩ resistor, detection range is about 5 m.
R-CDS: By adding a resistor (in parallel with the internal 1-MΩ resistor), user can change the light detection threshold as per individual requirement. This is applicable only when a light sensor is soldered in its pads (CDS) on the front of the circuit board. A 47–100K resistor works fine with standard 5-mm LDRs
