In the Ordinary Automatic Power Control , the working depends on a Sensor ,
This Sensor senses the object (Human) entering the Room - One Pulse is created , and the Circuit in ON state ,
Another pulse produced by the same pattern will turn off the circuit , it is done when the person leaves the room.
There is a problem though when more than one person enters the room.
Hence this problem is Solved in this useful circuit and explained easily
