automatic lighting system using atmega16
Introduction:
In today’s world we need to save electricity. Our project helps to achieve this purpose. In this project, microcontroller counts the number of person entering inside any room like conference room, seminar hall or classroom. The number of person is displayed on a liquid crystal display. When the number of person is equal to zero then the lights or fan inside the room are turned off using a relay. The counter used is bidirectional, this means that count will increase when person enters inside room and count will decrease when any person leaves the room. So whenever count is greater than or equal to 1 then the relay is turned on and respectively the light / fan are turned on.
This project is useful because many times we come outside the room and forgot to turn off the fan, thus we waste the electricity and power wastage. We can avoid this using our project “Automatic roomlight controller”.
