If the value is greater than 700, which means its day or bright, then the relay will not operate and the lights remain OFF. Learn more about relay here and how to connect an AC appliance to relay.

Automatic Light Coding. Arduino Uno is used to compute the logics of the two IR sensors. The circuit is controlled through the software loaded in internal memory of the Arduino. The program ...

In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. Such ...

This project involves creating an automated system that controls room appliances (like lights and fans) based on human presence using an Arduino microcontroller and a PIR (Passive Infrared) sensor.
