AUTOMATIC CONTROL OF ROOM LIGHT
                                                  ABSTRACT
The Project “Automatic Room Light Controller with Visitor Counter using Micro
controller” is a reliable circuit that takes over the task of controlling the room
lights as well as 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 in the room will be switched ON and when any one leaves the room then
the counter is decremented by one. 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 display. The microcontroller does the above job. It receives
the signals from the sensors, and this signal is operated under the control of
software which is stored in ROM. Microcontroller ATMEGA16 continuously
monitors the Infrared Receivers, when any object pass through the IR Receiver’s
then the IR Rays falling on the receivers are obstructed, this obstruction is sensed
by the Microcontroller.

1. INTRODUCTION
1.1 PROJECT DEFINITION:
        Project title is “AUTOMATIC ROOM LIGHT CONTROLLER WITH BIDIRECTIONAL
VISITOR COUNTER “.

      The objective of this project is to make a controller based model to count no
of persons   visiting particular room and accordingly light up the room . here we
can use sensors and can know present no of persons.

        In today’s world, there is continuous need for automatic appliances with
Increase in standard of living, there is a sense of urgency for developing...
