ABSTRACT
Home automation has been an important issue throughout the last two decades. Many solutions
have been reported and implemented [ 1-61. A power line communication network infrastructure for
smart home was reported by Lin and his team [ 11. The team used the existing electrical wiring and
outlets as the medium for data communication within the home where no new wires are needed and
many access points are available around the house. Other systems used conventional phone line for
monitoring and controlling home appliances [2, 31. Most recently, Internet and wireless
communications have been utilized in home automations [4-61. With the recent development in
mobile computing devices and mobile networks, new and better solutions can be developed to make
homc automation morc convcnicnt and acccssiblc on thc basc of 24/7 from anywhcrc at anytimc.
This paper presents one of the emerging applications of the GSM technology. We present the‘
design of a stand-alone embedded system that can monitor and control home appliances locally
using built-in input and output peripherals. Remotely, the system allows the homeowner to monitor
and control his house appliances via his mobile phone set by sending commands in the form of
SMS messages and receiving the appliances status as well.
The system has two parts, namely; hardware and software. The hardware architecture consists
of a stand-alone embedded system that is based on 8-bit microcontroller [7], an interface and a
driver circuit to connect the devices to the microcontroller, an LCD display, and a GSM modem [8].
The GSM modem provides the communication media between the homeowner and the system by
means of SMS messages. The system software driver is developed using an interactive C
programming language platfonn.
