Implementation of real time home surveillance and automation using GSM modem for dual communication / Anis Munyati Mohd Sabri

The focus of this paper is to present the design and implementation of real time home surveillance using GSM modem for dual communication, application for home security system. The concepts of this system using two way communications are mobile to-machine and machine-to-mobile communication. The system provides security against intrusion as well as automates various home appliances through SMS over GSM technology. 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. 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.
