5 PCS RCWL-0516 Microwave Radar Motion Sensor Module for Arduino Smart Switch Module Human Body Induction Module 5-7M Detection Distance 4-28V 100mA

This <b>5-Port Microwave Radar Detector Sensor Module</b> is designed for detecting human beings and the moving objects with the Doppler technique microwave induction. It has the features of high sensitivity, long sensing distance(5-7M), high reliability, wide detection angle and wide power supply voltage range(4.0-28.0V). It can be widely used for human body adaptive forward lighting system, security alarm system and so on.</br></br> <b>Parameters:</b></br></br> 1.Operating Voltage: 4-28V</br> 2.Operating Current: 2.8mA (typical);3mA (max)</br> 3.Detection Distance: 5-7m</br> 4.Transmitting Power: 20mW (typical);30mW (max)</br> 5.Output Voltage: 3.2-3.4V</br> 6.Output Voltage Driving Capacity: 100mA</br> 7.Trigger Way: repeat trigger</br> 8.Output Control Low Level: 0V</br> 9.Output Control High Level: 3.3V</br> 10.Operating Temperature: -20~80 celsius</br> 11.Storage Temperature: -40~100 celsius</br></br> <b>Adjustment Part Introduction:</b></br></br> <b>1. C-TM</b></br> 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</br></br> <b>2. R-GN</b></br> 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</br></br> <b>3. R-CDS</b></br> 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
