Automatic Room Light Controller With Bidirectional Visitor Counter

This Project - Automatic Room Light Controller with Bidirectional Visitor counter Counter‖ is a reliable circuit that takes over the task of controlling the room lights fans and other electrical devices as well us counting number of persons / visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light or fan in the room will be switched ON and when any one leaves the room then the counter is decremented by one. For example The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the LCD. The microcontroller does the above job. It receives the signals from the Door Switches, and this signal is operated under the control of software which is stored in ROM. Microcontroller PIC 16F continuously monitor the electrical signal Receivers. When any object pass through the switch then the switch send a signal directly to microcontroller. This obstruction is sensed by the Microcontroller.
