Product Review
This 5-Port Microwave Radar Detector Sensor Module 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. Parameters: 1.Operating Voltage: 4-28V 2.Operating Current: 2.8mA (typical);3mA (max) 3.Detection Distance: 5-7m 4.Transmitting Power: 20mW (typical);30mW (max) 5.Output Voltage: 3.2-3.4V 6.Output Voltage Driving Capacity: 100mA 7.Trigger Way: repeat trigger 8.Output Control Low Level: 0V 9.Output Control High Level: 3.3V 10.Operating Temperature: -20~80 celsius 11.Storage Temperature: -40~100 celsius 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
