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

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
