Microwave Radar Motion Sensor RCWL-0516

RCWL-0516 is a microwave motion sensor module which used the technology from Doppler Radar, with features of high sensitivity, long distance detecting, stability, large induction angle, wide working voltage and so on.

Applications

• Human detection as a trigger switch
• Security alarm systems

Features

• With Penetration detection capability, which not available from PIR sensor
• Detection distance adjustable
• Chipset: RCWL-9196
• Working Voltage: 4.0V – 28.0V DC
• Current: 30mA (Idle); 100mA(Working)
• Working Distance: 5-7 Meters
• Output voltage: 3.3V

Additional setting

• C-TM
  Adjust repeat trigger time, default 2s;
  Add on a capacitor will make repeat trigger time longer and actual counting trigger time as below:
    Solder a capacitor between C-TM, test 9196 3-pin frequency(f), repeat trigger time T=(1/f)*32768
• R-GN
  Detection distance adjustment, default 7 meters;
  Add on a resistor and detection distance will become shorter;
  If connect with 1M ohm resistor, detection distance is 5m
• R-CDS
  Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (9196’s pin-9) by R-CDS ,CDS connects with photoresistor, or you may disable detection function by timer (eg: night time)

Note

• Not to put any metal in front of the sensor
• * 1CM spacing is required in front and behind the sensor
• Not to use multiple microwave sensor at close range, suggest 1 meter distance between each sensor
