Design and Prototype Implementation of SMS Based Home Automation System

This research aims to design and implement a cost effective but yet flexible, adaptable, and secure Home automation system. Paper presents design and prototype implementation of a basic home automation system based on SMS technology. The proposed system consists of two main components; the GSM modem, which is the communication interface between the home automation system and the user. GSM modem uses SMS technology to exchange data, and signaling between users and home automation system. The second module is the micro controller, which is the core of the home automation system, and acts as the bridge between the GSM network (the user) and sensors and actuators of home automation system. Sensors and actuators are directly connected to hardware micro controller through appropriate interface. System supports a wide range of home automation devices; power management components, security, multimedia applications, and telecommunication devices. System security based on user authentication of each SMS being exchange, as each SMS contains user name and password (beside comments). User can easily configure home automation system setting through RS232 protocol using a user friendly interface.
