Automatic Room Light Controller With Microcontroller

Electricity being one of the most important resources must be utilized carefully.

Automatic room light controller with microcontroller.

Automatic room light controller section microcontroller turns on the room light when the person count is greater than or equal to one. Automatic room lighting system is a microcontroller based project that automatically turn on or off the lights in a room. This is done by relay. Today we are here with automatic room light controller project with bidirectional visitor counter by using arduino uno.

One is placed outside in front of the door and the other is placed inside the room. How they count the people and turn on or off the light when nobody is inside. And turn off lights when the count is zero. If a person enters into the room the ir sensors send the signals to the microcontroller such that the door opens.

Therefore an automatic room light controller automatically turns on the lights when a person enters into a room and turns off the lights when the person leaves the room. Arduino based visitor counter with automatic light control often we see visitor counters at stadium mall offices class rooms etc. This automatic room controller can be implemented by using a simple microcontroller and wireless ir technologies. Since the relay is used you can connect an ac bulb or dc bulb as per your requirement.
