We often forget to switch off lights or fans when we leave a room.
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.
And turn off lights when the count is zero.
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.
Home automation with automatic room light controller.
Automatic room light controller with auto door opening and closing the system depicted in the above figure comprises two pairs of ir transceivers.
This is done by relay.
Today we are here with automatic room light controller project with bidirectional visitor counter by using arduino uno.
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.
One is placed outside in front of the door and the other is placed inside the room.
If a person enters into the room the ir sensors send the signals to the microcontroller such that the door opens.
