Motor test platform monitoring system
Klecker, Jan ; Musil, Vladislav (referee) ; Pavlík, Michal (advisor)
The content of this thesis is to design system for temperature measurement of critical parts of NXP electric engine testbench. In the theoretical part will be analysed temperature measurement by temperature sensors and its connecting to microcontroller. The practical part is focused on realization of device for temperature measurement. This device will be based on NXP microcontroller from Kinetis MKVxx family.

Wireless meteostation
Holain, Martin ; Macháň, Ladislav (referee) ; Háze, Jiří (advisor)
The objective of this thesis is a design of the amateurish wireless weather station which is used to measure temperature, relative humidity, barometric pressure and velocity and direction of air flow. Part of this thesis also describes design of a device intended for display, processing and storage of actual measured data obtained from weather station.

Temperature control and monitoring system
Mitter, Martin ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This work is dealing with the design for maintaining and monitoring optimal temperature for home-based data center. The purpose of this work is to prolong the life of hard drives in data center for as long as possible. First of all, the attention is given to establishing what the optimal temperature for maintaining long-live of hard drives is and how to correctly measure it. Based on the knowledge obtained from theory and from the prototype testing the final design of embedded system for maintaining this function is created.

Effect of a switching arc on design of low voltage switchgear
Šimek, David ; Bartlová, Milada (referee) ; Aubrecht, Vladimír (advisor)
The first part of the master thesis is focused on theoretical analysis of the problems of diagnostics of an electric arc physical properties. In the thesis there is shown identification of spectral lines in experimentally measured electric arc spectra. The thesis deals also with energy balance of the arc. Next part of thesis is aimed to theoretical analysis of effects of electric arc on construction materials of low voltage electric apparatuses. The main part of thesis is devoted to experimental measurement of arc radial temperature changes, measurement of cathode temperature and research of electrical arc effect on selected construction materials of low voltage apparatuses.

CPU based system for river monitoring
Michník, Jakub ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This work presents hardware and software design for CPU based system for river monitoring with AVR microprocessor. It describes possible solutions for measurement of river characteristics, in particular water level height. Pressure method measuring and selection of important electric parts are described in more detail. The software for AVR microprocessor and also a program for PC which can distribute the measured data to the internet are described here.

Electronic thermometer and humidity meter
Lapáček, Petr ; Chmelař, Milan (referee) ; Lattenberg, Ivo (advisor)
This master´s thesis deals with the design of measuring station used for the temperature and humidity measurement. There is a theoretical basical description of sensores for temperature and humidity measurement in the first part. Furthermore I deal with a theoretical design of measuring system, especially with types of materials and possibilities of communication between these parts. The main part of thesis is about communication on buses I2C,UART, SPI, RS485. There is a description of function procedure of particular integrated circuit, moduluses which are used in task in the next part of thesis.In the practical part I was engaged in a functional design of autonomous system for the temperature and ralative humidity measurement. Data could be presented by the computer after connection with the station. There is a description of testing the particular circuits and the full description of function particular blocks of system in the task. I have used the program called Eagle for schemes and printed wirings designing. The copy is placed on CD ready for next using. In the last part of thesis is a brief description of program algorithm "Meteostanice", which I have created for data presentation. There is an illustration of measuring results in these last part. The task is completely ready for the realization of autonomous system of weather station with its own memory.

Communication devices over GSM/GPRS
Prečan, David ; Růčka, Lukáš (referee) ; Herman, Ivo (advisor)
This master thesis deals with a data remote transmission by means of SMS and GPRS technology. The overview of current solutions is presented and then a remote temperature measurement and a data transmission employing a communication module GSM/GPRS TM1 through GSM network using GPRS technology is described. As a response to an impulse, the communication module sends SMS. The technical solution is described in details including HW and SW design of the data transfer and processing equipment using a ATmega 162 microprocessor. This equipment communicates with a server (PC), which displays the measured temperature. A prototype which was used for a validation of the design is also described.
