Adjustment Part Introduction:
1.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
2.R-GN
Detection distance adjustment;connect with resistor and detection distance will become shorter;if not connect,detection distance is 7m;if connect with 1M ohm resistor,detection distance is 5m
3.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 detection function at night
Note: microwave modules cannot be large-scale applications in the same area, otherwise there will be mutual interference. Between single individuals over distance greater than 1M
