About this document
PIR Sensor Relay Control Code by Osama Yaseen is a document available to read on EtoBox.
This code sets up an Arduino circuit to detect motion using a PIR sensor connected to pin 2. When motion is detected, it turns on a relay connected to pin 3 and prints "Motion detected!" to the serial monitor. When no motion is detected, it turns off the relay and prints "Motion ended!" to indicate the sensor is inactive again.
