Small Temperature Test Chamber
Wolfshörndl, Robert ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This diploma thesis deals with the design of a small temperature test chamber. The first chapter is a study of temperature sensors suitable for realization of temperature chambers. The conclusion of this chapter is devoted to digital temperature sensor DS18B20. The second chapter deals with the principles and basic parameters of Peltier cells. In the third chapter design of individual electronic components of the temperature chamber is realized (circuit diagrams and PCBs), including a description of basic features of the microcontroller firmware. The fourth chapter is devoted to a description of the basic properties of the application software and a description of the communication protocol. The last two chapters deal with the construction of the temperature chamber and the results of final functional test.

Small Temperature Test Chamber
Lust, Radek ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis focuses on the methodology of determining the parameters of Peltier batteries and the theory of construction of a cooling block on the basis of obtained parameters. Gathered information is then used for design and construction of a small test chamber for laboratory purposes.

Thermostat for measuring passive component controlled of AVR
Demjanics, Ferenc ; Koňas, Petr (referee) ; Roubal, Zdeněk (advisor)
The aim of this work is to familiarize with the design of the thermal test chamber to measuring passive components. Show features and involvement of selected circuits that ensure reliable operation of the device. For the realization of the role are the most important the Peltier cells and temperature sensors. But they can not work without the control unit. The control unit provides the necessary communication with each component and also with user. For this purpose we made a selection of suitable type of microcontroller and communication equipment (matrix keypad, LCD, buttons and LEDs). Subsequently was designed the algorithm to control the thermostat suitable for using in students training. The algorithm was written in the microcontroller in form of a program. There is also implemented a PSD controller in the program, which evaluates the data collected by a sensor. Then set the correct function of Peltier cells. After the thermostat was designed and realized, test measurements were performed and the results were documented and evaluated.

Temperature stabilization system
Brtáň, Filip ; Kuchta, Radek (referee) ; Kadlec, Jaroslav (advisor)
This project deals with design of universal system for temperature stabilization using a Peltier device, controlled by microcontroller. The result of this work is an autonomous equipment with automatic tuning of regulation constants, calculation of temperature stabilization limits, possibility of setting required modes and with interface for connection to PC. The regulator stabilise temperature with an accuracy of 0,1 °C within the range of temperature from 0 to 60 °C.
