RCWL-0516 Microwave Radar Sensor Switch Module Human Induction Detector

RCWL-0516 microwave radar sensor switch module human sensor module intelligent sensor detector sensing distance of about 5-7 meters

Adjustment Part Introduction

• 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

• 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

• 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

Pin Definition

• 3V3:3V3 power output
• GND:ground
• OUT:control output;when detect moving objects,it will output high level
• VIN:input voltage,4-28V
• CDS:enable control chip,lower than 0.7V,OUT will output low level all the time
