AUTOMATIC ROOM DEVICE CONTROLLER

Abstract

This project is developed for the users to detect human being and to control the room light automatically. This project mainly consists of a pair of IR sensors, controller unit, Drivers and relays, fan and light. One sensor is connected at incoming door and the other is connected at the outgoing door. When any anyone enters, the sensor senses and sends signal to the controller. The controller sends signal to the fan and light unit through drivers and relays. When anyone comes out, the sensor sends signal to the controller and controller switches off the room light when the person in the room comes out. Thus the room light and fan will be ON even if one person should be inside the room. This project is very useful in complexes, houses, institutions etc. Since microcontroller is used, the operations are very accurate. This project is very cheap and cost effective.
