- 2. ABSTRACT This project demonstrates a novel method which enable users to control their home appliances and systems from remote 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 Global System for Mobile communication(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).

- 7. RELAY : •A relay is used to isolate one electrical circuit from another. • It allows a low current control circuit to make or break an electrically isolated high current circuit path.
- 8. GSM MODULE GSM is the most popular standard for mobile phones in the world. It is based on TDMA (time division multiple access) technology. We are using the SIMCOM 900, a GSM modem . This is a powerful GSM/GPRS Terminal with self-contained unit. This has standard connector interfaces and has an integral SIM card reader. The modem has a RJ9 connector through which a speaker and microphone can be connected allowing audio calls being established, but this feature is not utilized in this project as only data transfer is needed.
- 9. CONCLUSION Mobile phones have become an indispensable part of our life. Our system uses a controller and a cellular phone for its operations. The systems can be used as a test bed for any application that requires on- off switching based applications. Wireless controlled home appliances in the comforts of any environment will revolutionize our way of living. Controlling appliances remotely by a cell phone will one day become a reality and one should give thanks to the capabilities of HACS. HACS might one day become a standard system in the new homes to come.
