Abstract
This work presents the design and implementation of a GSM network-based home automation system for efficient monitoring and control of household appliances such as bulbs and fans. The motivation for this project stems from the growing need for remote and reliable home power management, especially in environments where physical presence is not always possible or convenient. The system was developed using a microcontroller, GSM module, power supply unit, and driver circuitry, with SMS commands serving as the communication interface. A key feature is the introduction of a 10-second delay mechanism after the first SMS to ensure smooth execution of subsequent commands. Experimental evaluation showed that the system achieved an average switching response time of approximately 10 seconds, with a reliability of over 95% in command delivery and execution. The results demonstrate that the system is practical, cost-effective, and suitable for residential and small-scale office applications, contributing to energy management and enhanced convenience in home automation.
