Automatic Room Light Controller With Microcontroller
If a person enters into the room the ir sensors send the signals to the microcontroller such that the door opens.
Automatic room light controller with microcontroller. Home automation with automatic room light controller. 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. Automatic room light controller with auto door opening and closing the system depicted in the above figure comprises two pairs of ir transceivers.
How they count the people and turn on or off the light when nobody is inside. We often forget to switch off lights or fans when we leave a room. And turn off lights when the count is zero. Electricity being one of the most important resources must be utilized carefully.
