RCWL-0516 Microwave Radar Sensor Switch Module/Body Induction Switch Module 4-28V

SKU: RCWL-0516
Mini doppler radar for movement sensing, 7 meter range, wide DC supply voltage.

Availability: In stock



Product Description


    Mini doppler radar sensor module with wide  DC operating voltage  4-28V.
    This mini radar motion sensor module is equipped with RCWL-9196 chip based on the doppler microwave induction technology.
    It will comtinuously output a high level TTL signal when there is motion. 360 degree sense area, no blind angle detection with a maximum 7m sensing distance alsdo with adjustable delay time and sensitivity. It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.
    1.The right side of the induction module should't be near any metal.
    2.The front/back side should a minimum of 1cm space


    • Operating Voltage: 4-28V
    • Operating Current: 2.8mA (typical); 3mA (max)
    • Detection Distance: 5-9m
    • Transmitting Power: 20mW (typical); 30mW (max)
    • Output Voltage: 3.2-3.4V
    • Output Voltage Driving Capacity: 100mA
    • Trigger Way: repeat trigger
    • Output Control Low Level: 0V
    • Output Control High Level: 3.3V
    • Operating Temperature: -20~80 celsius
    • 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:

    • 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
