Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The PIR sensor successfully detected motion and triggered the Arduino to turn ON the built-in LED. The LED remained OFF when no motion was present, confirming correct circuit and code functionality.

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...
