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

which not.

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

the following.

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.
