Firmware for a pressure sensor with HART interfacel
Čožík, Ondřej ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The bachelor thesis deals with draft of firmware for a capacitive sensor with HART communication protocol. At first, it briefly describes the HART protocol (principles of communication, frame structure and connectivity devices on the HART bus). Subsequently attention is paid to capacitive sensor description, method of data processing and communication method of the sensor with HART interface. The final part depicts individual parts of the firmware for the capacitive sensor (such as the method of values reading from A/D converter, data reading/writing from/to external or internal EEPROM or calculation of the measured pressure value, its temperature compensation and corresponding current loop, using D/A converter.

Two sensor temperature measurement
Novák, Lukáš ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This thesis deals with PCB design and programming of microcontroller AVR, that communicates with WiFi module and Dallas brand thermometers. Wifi module sends data to internet database. In case of communication malfunction informations are saved into microcontroler´s EEPROM. When communication is restored informations are send to database.

Design Thermally Insulated Chamber and Constant Temperature Regulation of Chamber
Vejnar, Pavel ; Dohnal, Petr (referee) ; Šedivá, Soňa (advisor)
The purpose of thesis is proposes a small temperature chamber with temperature control. The first part is focused on description Peltier cells, the theory of heat transfer and cooling. Next part of thesis is select suitable thermo-box and computes temperature resistance and includes simulation and real measuring. In next step is chamber simulate in program ANSYS and compare with real measuring. At the end is construct electronic control of temperature in thermo-box for constant value with programming program for the PC. The conclusion summarizes the results of the work.

Spectroscopic analysis of an electric arc
Hartman, Tadeáš ; Kloc, Petr (referee) ; Šimek, David (advisor)
The bachelor thesis deals with spectroscopic diagnostics of electric arcs. The first part explains the creation and properties of electric discharges, especially electric arcs. Methods for composition and temperature analysis of electric arcs are also given there. The next part deals with practical use of these methods for identification of elements contained in electrodes between which an arc discharge was happening, measurement of the arc temperature and also measurement of the temperature of the electrodes. In the last part, these methods are also used for the analysis of time progression of composition and temperature of an electric arc created on a contactor's contacts with the resistive load.
