Electricity being one of the most important resources must be utilized carefully.
Automatic room light controller with microcontroller.
Automatic room light controller with auto door opening and closing the system depicted in the above figure comprises two pairs of ir transceivers.
One is placed outside in front of the door and the other is placed inside the room.
Arduino based visitor counter with automatic light control often we see visitor counters at stadium mall offices class rooms etc.
Automatic room light controller section microcontroller turns on the room light when the person count is greater than or equal to one.
How they count the people and turn on or off the light when nobody is inside.
This is done by relay.
Automatic room lighting system is a microcontroller based project that automatically turn on or off the lights in a room.
Since the relay is used you can connect an ac bulb or dc bulb as per your requirement.
If a person enters into the room the ir sensors send the signals to the microcontroller such that the door opens.
Home automation with automatic room light controller.
Today we are here with automatic room light controller project with bidirectional visitor counter by using arduino uno.
We often forget to switch off lights or fans when we leave a room.
