Design and Implementation of Microcontroller Based Short Message Service Control System

This paper presents one of the emerging applications of the GSM technology. Ever since the invention of the mobile phone as well as SMS technology and the two-way messaging solutions it provides several creative solutions have evolved on how to apply this technology to revolutionize the standards of living and to solve other problems associated with manual control system. Controlling home and office appliances regardless of time and space is a serious challenge facing the world today; most especially in hazardous environment, or controlling of home appliances remotely and providing security when the user is away from the place. The control of home appliances using Short Messaging Service (SMS) is increasingly becoming not only an easy and comfortable way of control to the populace of several nations, but also a means of exposing another vital application of the SMS technology other than its most commonly use in sending and reception of text messages, and making calls by subscribers. The system will be used to provide ideal solution to the problems faced by home owners in daily life ranging from switching ON/OFF; water pumping machine, generator set, to controlling of home appliances like; Television, Lighting systems, etc wirelessly via SMS. When the action has been carried out, a response / feedback message is sent to the user mobile phone. A satisfactory result based on the design specifications was achieved after construction.
