HC-SR501 PIR Motion Sensor Pinout and Projects

The HC-SR501 PIR (Passive Infrared) Motion Sensor is a type of sensor that detects motion by measuring changes in infrared levels in its surrounding environment. It is commonly used in DIY electronics projects, particularly those involving Arduino boards.

The HC-SR501 PIR Motion Sensor typically has a detection range of up to 7 meters and a 120-degree detection angle. It also features adjustable sensitivity and delay time settings, allowing you to customize the sensor’s behavior to suit your specific needs.

To use the HC-SR501 PIR Motion Sensor with an Arduino board, you would typically connect the sensor’s power and ground pins to the Arduino’s 5V and GND pins, respectively. You would then connect the sensor’s output pin to one of the Arduino’s digital input pins, and use code to read the sensor’s output and trigger actions based on the detected motion.
