Nowadays, so-called intelligent home systems are being more and more popular. Its reasons can be the increasing energy prices, our need for a comfortable life, and the lowering prices of electronic devices.
In the last year, a home automation system has been developed at our department. Its goal is to satisfy the comfort needs. The system gives the user a one-button remote controller that gives users a really simple method to control their home appliances.
This solution has a serious disadvantage, that it uses wired control devices. Because of that, it can be hard to install this system to an existing house or flat. My task was to design and build a prototype of a wireless device that can be used to control electrical appliances and measure a few simple parameters of the environment, such as temperature and the level of illumination in the room.
First I had to read about existing home automation systems. Then I have selected the right solution for wireless connectivity and I have implemented it too. The next steps were theoretical design, hardware design, physical implementation and software development. Finally a modular electronic device was born which can perform required tasks with the cooperation of the central computer. Due to its modular build it has the possibility of further development or expansion.
