PIR Motion Sensors

PIR sensors detect motion by sensing infrared radiation from warm objects like people or animals. Ideal for automating lights, alarms, or smart systems, these sensors are a simple yet effective way to add motion detection to your electronics project. They work seamlessly with microcontrollers like Arduino and Raspberry Pi, and often include adjustable sensitivity and delay timers for flexible use.
