Automatic Room Light Controller With Single Door Bi-Directional Visitor Counter

65 comments:
Automatic Room Light Controller with Single Door Bidirectional Visitor Counter is a reliable circuit that takes over the task of counting number of persons/ visitors in the room passing through a single door and also turns ON the room light when there is at-least one person in the room and turns OFF when the room is empty. The total number of persons inside the room is displayed on seven segment display. We can use any other appliance like fan or anything else instead of the light.
Watch this video to get an overview of this circuit.
