  This research work investigates the potential of Full Home Control, which is
the aim of the Home Automation Systems in near future. The analysis and
implementation of the home automation technology using Global System for Mobile
Communication (GSM) modem to control home appliances such as light, conditional
system, and security system via Short Message Service (SMS) text messages is
presented in this paper. The proposed research work is focused on the
functionality of the GSM protocol, which allows the user to control the target
system away from residential using the frequency bandwidths. The concept of
serial communication and AT-commands has been applied towards the development
of the smart GSM-based home automation system. Homeowners will be able to
receive feedback status of any home appliances under control whether switched
on or off remotely from their mobile phones. PIC16F887 microcontroller with the
integration of GSM provides the smart automated house system with the desired
baud rate of 9600 bps. The proposed prototype of GSM based home automation
system was implemented and tested with a maximum of four loads and shows the
accuracy of greater or equal 98%.
