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 objective of this project is to enable users to remotely control their home appliances and systems using a cell phone-based interface. To access the control unit, the user should send an authentication code along with the required/desired function/action to his/her home control system via GSM. Upon being properly authenticated, the cell phone-based interface at home (control unit) would relay the commands to a microcontroller that would perform the required function/action, and return a function completion code that would be sent to the source of the original command (user’s cell phone). There is also some feature which send the sms to the user when there ocur abnormal event in house like firing and theif..
