Automatic Room Light Controller Circuit and Applications Circuit Diagram The code for the Automatic Room Lights using Arduino and PIR Sensor is given below. Working of the Project The Automatic Room Lights using Arduino and PIR Sensor is a simple project, where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left or there is no motion.

So, I had this idea for an automatic light controller using an Arduino and an ultrasonic sensor (HC-SR04) to turn on a light whenever someone crosses a certain distance. The idea was pretty simple: you walk near the sensor, and it detects your presence, automatically turning on a lightโperfect for when you need a little extra brightness, like at the stairs or in a dark room.

Automatic Room Lights using Arduino and PIR Sensor Circuit Diagram
Automatic Room Lights using Arduino and PIR Sensor is to be used where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. This Automatic Room Lights can be implemented in your garages, staircases, bathrooms, etc. where we do not need continuous light but only when we are present
The Automatic Room Light Controller using Arduino and IR Sensor is a simple project, where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left or there is no motion. Working of this project is very simple and is explained here. Initially, when there is no human movement, the IR Sensor doesn't detect any person and its

How to make Automatic Light Control using Arduino and LDR Sensor ... Circuit Diagram
The aim of this project is to automatically turn on or off the lights in a room by detecting the human movement. We implemented this project using 8051 Microcontroller and two Infrared (IR) sensors.. Since the job of the circuit is to turn on the light when someone enters the room and turn off the light when the last person leaves the room, the project has to internally count the number of
