PIR Motion sensor module (Adjustable Range) 7413 Signal pin will output thePIR "Passive Infrared"sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. How to Use PIR Sensor The PIR sensor have 3 pins: Power: 3 5 VDC Output: High (when motion detected) Low (no motion detected) Ground: connected to ground The output pin will go "high" to 3. 3V and light up the LED when motion detected. Specifications: Input Voltage: DC 3 5V Output signal: 3. 3V (motion
