Smart homes are getting more and more attention, as the technological process makes
reliable and useful products available in the area. Despite the wide variety of technologies,
it is still not clear, which has the ability of a widespread, global future application, and
Wired and wireless technologies are both available, and prevalent, but the first gets
overshadowed by the new wireless line of bearing (generally in information
technologies). However, wired technologies tend to be faster, and more reliable still.
In home automation or smart home applications, there are two ways of wired solutions.
Either using separate cabling or the main power line. If the latter can be dependable, and
widespread, a lot of existing households can be easily upgraded to become smart homes
without radical reconstruction of the wiring in the walls.
This final project focuses on designing a power line based circuit, for testing the
complexity and the possibility of a universal device. The objectives of the project include
Understanding the smart home concept and the power line communication, scheming the
filters connecting the main power line and the device, choosing microcontroller and
modem IC for the purpose, understanding the operation of them, and designing a software
that makes basic communication possible.
For this purpose, a prototype circuit is completely designed, then efforts are made to
implement the communication, limited by the prototypes capabilities.
