[attachment=25412]
Abstract
This paper presents the development of GSM-based control home appliances for smart home system. The main aim of the prototype development is to reduce electricity wastage. GSM module was used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, air-conditioner etc. The system was integrated with microcontroller and GSM network interface using assembly language. MPLAB software was utilized to accomplish the integration. The system is activated when user sends the SMS to controller at home. Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical home appliances by switching ON or OFF the device according to the user order. In other word, it read message from the mobile phone and response to control the devices according to the received message. The prototype has been successfully developed and it could provide an effective mechanism in utilizing the energy source efficiently.

1. Introduction
The development of digital information has led the rapid change in human lifestyle. The use of electricity is very important as one of the main source of energy that is vital in today modern life. Some kinds of mechanism using available technology could be used to reduce wastage in electricity usage. Thus a prototype based on a microcontroller device using SMS is developed. It can automatically control any electrical equipment at home remotely using mobile phone. Hence the electrical energy saving in daily life can be made more efficient and effective.
As the technology grows, SMS technology has been widely accepted as a part of medium of communication [1]. The purpose of using SMS is to provide widest coverage at minimal cost. Therefore the use of SMS would facilitate in controlling the electrical device at home from long distance and low in maintenance and independent from any physical geographical boundary.
At the present time, people use electrical energy as one of the main source of power of energy to operate any electrical device or appliance. Most of the people turn on the light for 24 hours per day when they are away from home. Leaving the light turned on continuously, lead to energy waste. Thus this project is proposed to develop a system is to facilitate the home owner to optimize usage of electricity remotely using SMS.

SMS application to securely monitor the home condition when the owner are away or at night. A system as suggested by [2] triggered by SMS to the home owner to notify the owner of any incident happened around the house such as robbery or fire. The security system uses mobile phone with a combination of microcontroller circuit PIC16F877A which interfaced with the computer. The system work accordingly when the sensor actively triggered by any abnormal activity, then the PIC circuit also automatically activate the computer to send SMS to the owner using mobile phone modem.
Meanwhile, the system developed by [3] is automating the power reading meter to send the energy consumed to e-billing system at authorized office. The system works by integrating the GSM modem that was embedded with digital kWh power meter. It utilizes the GSM network to send power usage reading using SMS to the authorized office. The authorized office collect and manage the received SMS message contains the meter reading to generate the billing cost and send back the cost to the respective consumer through SMS. The work presented by [4] is about the development of Integrated Water Billing System with SMS capability. The system is designed to facilitate the Water authorized to manage the monthly billing system without the use of human services. The system receives SMS from the meter to central databases. Then the information received is processed to generate current billing. The system again sends a SMS notification to the user regarding the total amount that has been billed. The system was implemented using Visual Basic and database in order to perform the prototype and the system works successfully in sending SMS to user for notification.
Furthermore, the system developed by [5] is to control the switch for lamp, door and alarm system using Visual Basic 6.0 software. Visual Basic was chosen because it can easily communicate between computer and mobile phone. The system used computer and mobile phone to send and receive the text messages.
Vehicle Speed Detection using SMS [6], presented the design of the black box for warning system to control the exceeding speed of express bus via SMS. The system consists of three main parts which is microcontroller circuit, relay driving circuit and also mobile phone. This project used PIC 16F873A, Nokia 3310 mobile phone and using JAL (Just another Language) software for the programming. The purpose of this project is to prevent the express bus driver from driving over the permitted speed limit as well as to educate the drive to obey the regulation; therefore the accident can be prevented as well. The system is activated when the speedometer in the black box exceeds the speed limit permitted by Department of Transportation (JPJ), thus, SMS text notification is sent to JPJ for record.
Moreover, the projects for Acquiring Water Level and
Temperature Status via SMS [7] also has similarity with this project. This project utilized PIC 16F877 and MPLAB IDE software for programming. The project was designed to detect level and temperature of the water in a pool. The system functions when the level of water and the temperature in pool exceed the desired limits. At the same time the PIC circuit will automatically interface to the mobile phone and send the alert message to the user.
A very similar project also have been implemented by Serasidis Vasilis [8], who has developed and designed a device that can control variety of electrical home appliance using SMS. The system works based on the order message from user through mobile phone which is ON or OFF. This system also utilized mobile phone as a receiver which connected to the microcontroller. The circuit can control 8 electrical home appliances at any one time. It is used AT 9052313 microcontroller and Ericsson T10s mobile phone as a receiver at home. The software for programming that was used is MPLAB IDE.
Besides that, Noraini [9] presented the used of RS232 devices computer and controlling system as hardware and RS232 interface with Visual Basic 6.0 as software to control lamp and fan. The system activates when microcontroller send ON or OFF to the devices via computer.
