HOME AUTOMATION SYSTEM USING ARDUINO UNO

Some people are always on the move from place to place due to business demands. They may have to spend a couple of days away from their home leaving all their household appliances without any kind of monitoring and control. Some devices are supposed to be left into the power sockets but there are many devices which need not be plugged in all the time. This may require an individual to manually attend to each of the devices independently from time to time. All such monitoring and control can be done without necessarily being around or inside the home. Therefore an Internet based home automation system to manage appliances remotely from anywhere, anytime is needed. Home automation has been implemented in a variety of ways, some of which include: Bluetooth, GSM, Wi-Fi, ZigBee. Though all of them are prevalent, but there are constraints regarding each of them. The significant constraints are related to range of operability, additional costs, delay in receiving commands and security. In order to overcome these constraints a system should provide a user friendly and easy way to give commands which can be executed immediately from anywhere in the world, given that there is an internet connection. This system should not be confined in terms of range. The proposed system is a distributed home automation system which consists of a microcontroller based hardware side and a website which forms the software side of the project. The system will be accessible from remote locations via web interface. The microcontroller will be interfaced with a GPRS module to bring it online and will have various relays and sensors to achieve the objective
