RCWL-0516 Microwave Radar Sensor Human Body Sensor Module Induction Switch Module Output 3.3V for Arduino Diy

RCWL-0516 microwave radar sensor switch module human body sensor module smart sensor detector sensing distance is about 5-7 meters

RCWL-0516 microwave induction module:
RCWL -0516 is a microwave sensor module that uses Doppler radar technology to detect the movement of objects.
The module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle, and wide power supply voltage range. It is widely used in various situations such as human body induction lighting and anti-theft alarm.

●Using dedicated signal processing control chip RCWL -9196
●Wide operating voltage range: 4.0~28.0V
●Compared with traditional infrared induction PIR, it has penetration detection capability
●Block time, distance can be described
●Can output 3.3V power

Pin function description:
1: 3V3
3.3V output voltage, drive current 100mA.
2: GND
Module ground.
3: OUT
Control signal output, when there is an object moving in the detection area, OUT output high level: C-TI can set the repeated trigger time, if there is a trigger signal (object moving) within the repeated trigger time, continue to output high level: if detected There is no moving object in the area, and the output is low.
4: VIN
Module power input, 4-28V.
5: CDS
Trigger control signal: less than 0.7V, 0UT output low level all the time: greater than 0.7V, the detection works normally. The CDS pin is connected to a photoresistor, which can turn off the module detection function at night.
