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.
