Abstract

This project aims to develop and to design a smart home system by sending short message service (SMS) via global system for mobile communication (GSM modem) to invent the security system for home owners. The concept of smart home is an emerging issue to the modern technology dependent society. Remote control technologies are widely used to control household electronic appliances without walking up to them. Controlling household appliances through computer can also be a possible solution. However, it cannot fulfill the current demand which is to control them from remote places. The advantages of cellular communications like GSM technology is a potential solution for such remote controlling activities. GSM and SMS technology can be used to control household appliances from remote places. GSM modem was used for receiving 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, and fan. 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 security home.
