The main task is to design two-state temperature controller, which consists of two parts, a thermometer unit and a switching unit, and these units communicate with wireless network.
The first chapter presents the evolution of temperature regulation and gives a general description about thermostats. This also mentions when the first temperature controller was created, and what types of switches and thermometers is in use nowadays.
More specifically, the aim of the second chapter is the examination of the commercially available thermostats. Here I present the pros and cons of each type of two manufacturers, namely, Siemens and Computherm through their products.
The third chapter specifies a wireless two-state temperature control device by the properties of the examined products, which useable in ordinary conditions and provides opportunities for future developments.
The fourth part discusses the design steps of the specified thermostat, with some introduction to the theory of two state regulations. As a first step, I present a “block-frame” for the planned components of the two units, to make it transparent the operation of the whole system, and after that the method of component selection follows. The end section contains the edition of schematic and the manufacturing of printed circuit board.
The fifth chapter presents the details of designing process of controlling software for the finished hardware. It discusses the main features of the devices, the main programming steps, the results and the circumstances of finished software testing.
