Description

• RCWL-0516 is a microwave motion sensor module which use the technology from Doppler Radar.
• with feature of high sensitivity, long distance detecting, stability, large induction angle, wide working voltage .
• The microwave antennas are integrated onto the small printed circuit board, making it a completely self-contained unit.
• It’s widely used in kinds of human lighting switch and burglar alarm systems and devices.
• The CDS pins are where you can attach an optional light sensor, a light dependent resistor (LDR).  The LDR can actually be hooked up two ways:
• • • Using the two CDS pads on the top of the sensor printed circuit board.
    • By connecting one end to the CDS pin on the main terminal section and the other end of the LDR to ground.
• The light sensor will disable the device when it detects ambient light. You may also use the CDS pin as an Enable control for the module.
• C-TM
  • • Adjust repeat trigger time, default trigger time is 2s.
    • increasing capacitor’s capacity will make repeat trigger time longer.
    • 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 connected, detection distance is 7m.
    • If connected 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
