Energy Efficient Home Automation Using IoT

India is the 4th largest consumer of energy, so it has to strive relentlessly for alternative methods to achieve effective reduction in consumption of energy. Because of inadequate energy infrastructure and extensive energy usage, intelligent energy management systems need to be incorporated in order to use energy more efficiently and to make an effective safe environment not only in industries but also in other ways of our day to day lives. Smart home automation can manage and monitor household energy efficiently and it also ensures safety. In this paper, an intelligent home automation technique is implemented using Internet of Things which will overcome the existing energy usage problems to a great extent. IoT makes use of a combination of intelligent software applications along with electronic devices to build an effective data exchange network. To implement this, a low cost and low power consuming embedded Wi-Fi module ESP8266 is used to operate a relay channel, which acts as a switch to control household appliances. Here Thinger.io provides cloud infrastructure through which mobile and ESP8266 to communicate with each other via REST API.
