Home automation system is becoming popular day by day all-over the world. Starting from simple home to large industrial setup everywhere Home Automation is used in a large number. With the advancement of technologies home automation system are gradually advancing more and more, making the life of every individual smoother and easier with minimizing the work load. Home automation refers to the automatic and electronic control of household appliances, features and activities which is initially developed with the aim to provide supporting system for the elderly and disabled, especially those who live alone but now a days it also fulfil the requirement of a large number of population seeking luxury and sophisticated home automation platform. The main objective of the project is to provide the necessary freedom of controlling devices in home or industry like tube light, electrical bulbs, electrical fan, AC etc. automatically using different sensors like PIR, DHT 11, wit the Arduino UNO platform by sensing the presence of individual. The device is made smart enough to detect human presence using PIR sensor and measuring different other parameters like daylight, temperature etc to control Electrical bulbs and the speed of fan. The proposed prototype also come with a LCD display to make the user to see the different values of measured parameters like temperature etc. The device also enables the user to manually control different activities like ON/OFF lights and speed of fan. The device is also a cost effective model to make it possible to implement by everyone according to there requirements
