The automatic room power controller
It controls your over consuming light and reduces your power electricity bill.
It consists of the ic and some sensors which automatically sixth off your lights and fans when you reach not in your room. It also consists of counter to count how many people are coming in out.
Display LCD panel is shown there.
Relays work perfectly when light is on off.
Hope you like my project

How do you read the current and the voltage? What sensors do you use?
I have used ir sensors they are not visible in it they are hidden under the cover... to detect the signals
Ok, I thought you read the current and voltage of the circuit. Another question, how do you feed the ic? I see you use a transformer, how do you do the rectification? Good post but you could put more information, it's very interesting.
