RCWL-0516 Microwave Radar Sensor Module Body Induction

RCWL-0516 Microwave Radar Sensor Module Body Induction

• RCWL-0516 microwave radar sensor switch module human body induction module intelligent induction detector, sensing distance of about 5-7 meters
• Summary: RCWL-0516 is a Doppler radar technology, specialized in the detection of moving objects in the microwave induction module.
• The module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various kinds of human body induction lighting and alarm and so on.
• Characteristic:
• Using special signal processing control chip RCWL-9196
• Wide operating voltage range: 4-28V
• Compared with the traditional infrared induction PIR, the penetration detection ability
• Blocking time, adjustable distance
• Can output 3.3V power supply

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
