This document describes a home appliance control system based on GSM network technology. The system allows users to remotely control and monitor home appliances and security via SMS messages sent from their mobile device to a GSM modem connected to a PC system in the home. When intrusions are detected by the system, such as at the main gate, entrance door, or windows, an SMS alert is generated and sent to the user's mobile phone. The GSM-based system provides an affordable way to remotely control home automation and security compared to previous methods. Future improvements could integrate the PC and GSM modem into a single enclosed device with its own UPS and charging system.
