Wiring Diagram
The PIR sensor can be connected to a microcontroller such as an Arduino. The wiring involves connecting the VCC to a power source, the OUT pin to a digital input pin on the microcontroller, and the GND to ground.
Functionality
The PIR sensor detects motion by measuring changes in infrared radiation. When a heat source, such as a human body, moves within its detection area, the sensor outputs a digital signal.
Diagram Description
The diagram illustrates the detection area of the PIR sensor using a Fresnel lens. It shows how the sensor detects movement and produces an output signal in response to changes in infrared radiation.
Example Setup
An example setup includes a PIR sensor connected to an Arduino board. The wiring involves connecting the sensor’s pins to the appropriate pins on the Arduino and using a breadboard for connections.
