Automation Controller System
What is GSM ?
GSM, which stands for Global System for Mobile
Communications, is a digital cellular radio network
operating in over 200 countries world-wide. It provides
almost complete coverage in western Europe, and growing
coverage in the Americas, Asia and elsewhere.

2. Of special interest is the capability of the GSM network to
be used for data computing. Most people think of voice
calls when they think of cellular phones. But because GSM
is digital, you can connect your GSM-enabled phone to
your laptop computer and send or receive e-mail, faxes,
browse the Internet, securely access your company's
LAN/intranet, and use other digital data features including
Short Messaging Service.

3. The unique roaming features of GSM allow cellular
subscribers to use their services in any GSM service area in
the world in which their provider has a roaming agreement.
That means the phone you use in France could work in
Germany, Australia, Finland and even China, depending on
your provider's roaming agreements.
GSM-enabled phones have a "smart card" inside called the
Subscriber Identity Module (SIM). The SIM card is
personalized to you and you alone. It identifies your
account to the network and provides authentication, which
allows appropriate billing.
Aim of project
Imagine being able to control all the electrical appliances of
your home from virtually any place your are in the world!
For example, say one cold winter day, you are stuck in
traffic on the motorway after a long day at work. By
pressing a few keystrokes on your mobile phone, you
activate a macro which turns on the heating, prepares your
Jacuzzi, switches on your electrical fireplace and lava-
lamps at your premises.
In today's times the GSM mobile terminal has become one
of the items that is constantly with us. Just like our
wallet/purse, keys or watch, the GSM mobile terminal
provides us with a communication channel that enables us
to communicate with the world. The want for a person to be
reachable or to call anyone at any time is very appealing.

4. Using the cybernetic concept of action space, we in fact
extend the action space of the human with the mobile
terminal, enabling the subscriber to talk to another
subscriber and thus exchange information, issue or receive
commands.
In this project, we will explore ways of extending this
notion of Home Automation by applying mobility to it
using various technologies that are available in our
information age. These technologies include mobile
communication devices and the Internet which are
becoming part of our everyday lives.
Working of the project:
As mentioned earlier our project consist of
sensors for detecting abnormal situations and the data
is sent to a remote user through a GSM Modem
connected to the project. (Intruder sensed, Flame
sensed).
Also the user can send a SMS Message to
activate a device which is connected to the project.
For eg a Tubelight or fan any electrical device. The
user gets a reply SMS on his phone whether the
device is switched on or off.
