RCWL-0516 microwave radar sensor module Human body induction switch module Intelligent sensor

Product Introduction:
1.Operating Voltage:4-28V
2.Operating Current:2.8mA (typical);3mA (max)
3.Detection Distance:5-9m
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

Pin Definition:
1.3V3:3V3 power output
2.GND:ground
3.OUT:control output;when detect moving objects,it will output high level
4.VIN:input voltage,4-28V
5.CDS:enable control chip,lower than 0.7V,OUT will output low level all the time

Notice:
1.The right ahead of induction side should't place any metal to block
2.The front/back side should reserve more than 1cm space
3.Module and installation carrier
