Towards the development of an energy-efficient smart home through IoT

Smart home is one of the emerging technologies in the Internet of Things (IoT) era that decorates house equipment into being more intelligent, remote controllable, and interconnected. For this reason, researchers have made significant advancement in developing smart home. However, there is scarcity of a complete system in the market that provides a total solution. In this paper, a complete 3-room apartment automation system developed using Arduino, Bluetooth and Android has been proposed. Our proposed system can control several home appliances such as lights, fans, bulbs and many more using on/off relay and android application. The system has been implemented for a 3-room apartment that confirms cost and energy efficient than the manual system which is 28% less in terms of cost.
