Universal Microcontroller Unit
Kulenda, Vít ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
Master’s thesis contains description parameters of microcontroller ATMEGA644P, also contains differences between older and newer version of microcontrollers ATMEGA644 and ATMEGA644PA. Inside structure of microcontroller, memories and peripherals are described here. The construction of the universal microcontroller unit is main target of this thesis. The unit contains supply, A/D converter, current loop, communication interfaces, temperature sensor, accelerometer and other. The unit collects and saves data, communicates by interfaces and manages other functions. Using devices and circuits are described in this thesis. Development of software for microcontroller(firmware) are positioned to last part of this thesis. This software control functions of all parts positioned on the unit.

USB thermometer
Holub, Jiří ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with a problem of electrical measurement of temperature. It describes a various types of temperature sensors and processing data obtained from these. It describes in short the USB interface and its parameters. It also contains a design of hardware and software solution of thermometer using temperature sensor SMT 160, managed by microcontroller ATmega16 and communicating with PC via USB interface. Designed thermometer also offers possibility to save measured data to built-in memory and later load them from there. Measured data will be also displayed on LCD. Last part of these thesis is design of application for PC, which will serve for displaying measured data and adjustment of thermometer.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.

Calibration of temperature sensors
Záboj, Jakub ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
How the change of temperature works on physical properties of substance and materials is described in this bachelor’s thesis. Historical development of thermometers and measuring of temperature that goes to the standard temperature scale. There is summary of today's ther-mometers and their detailed descriptions. Select calibrators follow as an instrument for check and calibration temperature sensors (thermome-ters). For example there is described calibration of thermocouple, where we put at their self - characteristics of thermocouple. The most frequen-cies mistakes during calibration are summered there and also description between different calibrations methods finally.

Erors and Uncertainties in Temperature Measurement
Jirmásek, Jakub ; Vojáček, Zdeněk (referee) ; Vdoleček, František (advisor)
Bachelor thesis is focused on sources of temperature measurement uncertainties and their expressing. There is a basic description of the temperature as a physical quantity and its scale. The study describes some kinds of thermometers, focusing primarily on electric thermometers which have a dominant position in the field of automation and regulation. Further the importance of measurement uncertainty is described and its expressing. More space is devoted to the importance of different sources of uncertainty and possible compensation. Finally there is an example of determining the measurement uncertainty.

Termometer with graphical display
Křeček, Libor ; Havránek, Zdeněk (referee) ; Macho, Tomáš (advisor)
The aim of this bachelor thesis is to provide an insight into the measurement of the temperature in the range. In addition to design a digital measuring device that would measure and display the temperature on a graphic LCD display, also to create the manufacturing documentation and provide proposed system implementation, including the production of PCB. Due to the use of microprocessor technology the controller software debugging is required. The measured temperature range is -40 to +120 °C with an accuracy of better than 0.5 °C.

Comparative study of body temperature measurement using various technologies
Vaněk, Ondřej ; Sekora, Jiří (referee) ; Provazník, Ivo (advisor)
The aim of this work is to compare the body temperature measurement with different contact thermometers. The theoretical part includes studying the topic, familiarization with the situation at the Faculty Hospital Brno, Bohunice and suggestion of method for comparison. The practical part includes thermometers measurement in the laboratory to verify the accuracy, clinical measurement on patients in different parts of the body and under various conditions and statistical evaluation of results.

Temperature Measurement with Microcontroller Aid
Harčár, František ; Holý, Miroslav (referee) ; Zuth, Daniel (advisor)
The thesis focuses on possibilities how to use inexpensive microcontrollers for temperature measurement. The designed module is appropriate both for laboratory curriculum, as well as for application in automation industry. A brief introduction is followed by a general explanation of the notion „measurement“ and a measurement history overview. Afterwards, there is a focus on history and development of temperature measurement and types of applied sensors. Conseguently, there is the thesis itself , its description, principles, connection schneme and measurement methodology. Finally, the thesis regards its commitment and findings.

Upgrade Thermal Chamber
Pagáč, Radek ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
The target of this work is to modernize air-conditioning control of the unit Thermal Chamber. The old air-conditioning unit will be renewed by replacing old one by new one, microcontroller-driven control unit, trough which it will be possible to show the current and desired temperature LCD. Theoretically description of the components and methods of measuring the temperature and environment for the creation of the microcontroller is shown before construction.
