Automatic washroom light control project kit

This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains.

Whenever a person enters the washroom, the light bulb (or tube light) will automatically turn on. When the person leaves the bathroom, the light will turn off. This will save electricity charges due to the light remaining on by mistake after use of the washroom.

In this project, will show you how to design and build a simple Automatic Washroom Light Switch Circuit, which will automatically turn on the when you enter the washroom and turns it off when you leave

We turn on the lights in our washroom when we enter it and turn them off when we leave. Sometimes, we forget to turn the lights off after leaving the washroom.

This may lead to power wastage and also the lifetime of the light bulbs may decrease. To avoid these problems, I will show you how to make a simple circuit which will automatically turn the lights on when a person enters the washroom and it automatically turns it off when he/she leaves it.

By automating the process this way, there are many advantages like, the person need not care about turning the light on or off whenever he/she is using the washroom. The circuit, which you will know about in a moment, does it automatically for that person.

The circuit is also designed to consume lesser power so that the circuit can be used in any household or public washrooms without worrying about the power bill.
