IOT based Automation for Smart Sustainable Homes

This paper proposes the design of Inter of Things (IoT) based home automation system using Raspberry pi. Unlike the conventional fixed switches for switching on and off- fans, bulbs and other electrical devices , it would provide users portable control and management all the devices connected together over wireless local area network. Moreover this paper lays emphasis on the security of the user’s home by providing biometric door lock/unlock feature through fingerprint sensor of a smart phone. This paper also include a water tank management system with objective to send notifications to the user about water level with option of automatically cutting off the power supply at full tank level thereby preventing any water wastage. The main objective is to provide the users with a simple graphical user interface in form of a mobile application that will allow them to control and automate their household devices, provide them with security features and prevent wastage of natural resources like water and electricity with just a simple touch on their smart phone which eventually make smart homes sustainable too.
