Using the convenience of SMS, this project lets you remotely
control equipment by sending plain text messages, such as "pump on", "aircon
off", "reset" or "blast horn" – all of which can be pre-programmed into the
controller and easily remembered later. It can control up to eight external
devices and report the condition of up to four digital inputs.
Short Message Service (SMS) is defined as a text-based service
that enables up to 160 characters to be sent from one mobile phone to another.
In a similar vein to email, messages are stored and forwarded at an SMS centre,
allowing messages to be retrieved later if you are not immediately available to
receive them. Unlike voice calls, SMS messages travel over the mobile network’s
low-speed control channel.
"Texting", as it’s also known, is a fast and convenient way of
communicating. In fact, SMS has taken on a life of its own, spawning a whole new
shorthand language that’s rapidly being adopted as the norm.

Australians have been quick to make use of this technology,
with millions of handsets currently in use. As new models with "must have"
features hit the market, older models become virtually worthless and if not
recycled, end up in landfill.
With this in mind, we’ve designed the project to work with
several popular (but now outdated) Nokia models. Chances are, you’ll already
have one of these on the shelf. If not, secondhand units are readily available
for a song.
