Implementation of real time home surveillance and automation using GSM modem for dual communication: article

The focus of this paper is to present the design and implementation of two ways communication based on GSM (Global System for Mobile) used hand phone Sony Ericsson E300 as a modem application for home security system. The motion, magnetic and vibration sensor are defined as input variables and the fan, lamp and buzzer is defined as output variable. This system offers a complete and user friendly way of 24 hours real time monitoring and controlling of a home security. The concepts of this system using two way communications are mobile-to-machine and machine-to-mobile communication. First, develop a general purpose electronic circuit design that can monitor and control a variety of home appliances with interface that can be plugged into GSM hand phone unit which is Sony Ericsson E300i. The design has been described using PIC (Programmable Interface Controller) comprises microcontroller, adaptation circuit, power circuit, MAX 232 and RS232 interface. Then, develop prototype home security as an application example of the designed PIC system. The system is completely built and tested and showed perfect operation.
