This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

This project demonstrates a simple motion detection and alarm system using an Arduino Uno and a PIR (Passive Infrared) sensor. When motion is detected, the system activates a buzzer and an LED to ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.
