RCWL-0516 Microwave Radar Human Sensor Module

RCWL-0516 is a doppler radar microwave motion sensor module which can act as an alternative to a PIR motion sensor. It’s not just a super charged alarm sensor, it can be used to switch lights and very much anything else you want to trigger by movement.

Working voltage: 4 – 28V. It provides a convenient 3.3V output to drive a microcontroller.

The forward side of the microwave sensor module is the side with the components. This side should face the objects being detected. Do not obstruct the forward side with anything metallic. The back side should have a clearance of more than 1cm from any metal.

Microwave sensor module specification:
1.Operating Voltage:4-28V
2.Operating Current:2.8mA (typical);3mA (max)
3.Detection Distance:5-9m
4.Transmitting Power:20mW (typical);30mW (max)
5.Output Voltage:3.2-3.4V
6.Output Voltage Driving Capacity:100mA
7.Trigger Way: repeat trigger
8.Output Control Low Level:0V
9.Output Control High Level:3.3V

Adjustment Part Introduction:

On the back of the board (the side without components) are pads for 3 optional components (0805 dimensions).

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
