Measurement of meteorological variables
Škorpík, Daniel ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor thesis discusses about the basic meteorological variables, especially temperature and airflow. These magnitudes are measured using an anemometer which uses resistive sensors, namely, two thermistors of NTC type that described technology, operations, methods of scanning, sensor placement and implementation of such a device. After that was designed block diagram and circuit diagram. The meter is realized, than we describe the individual components and then is calibrated and tested. In conclusion, it is evaluated for use in medicine.

Wireless stopwatch
Hampl, Tomáš ; Pristach, Marián (referee) ; Bohrn, Marek (advisor)
This bachelor thesis describes the design and implementation of the system of the wireless digital stopwatch for timing. Stopwatch is implemented by microprocessor ATmega16 and the wireless transfer of data by module RFM22. The theoretical part of the work is focused on the description of the all used technologies. The practical part is focused on the design and overall realization of the system. For the processing of the measured results is programmed user application. The final result is the functional prototype of the device including software for microprocessors and computer.

Planar LED Display Application
Houserek, Jiří ; Kosina, Petr (referee) ; Šandera, Josef (advisor)
This coursework deals theoretical with design and construction of the electronic clocks controlled by DCF77 signal, which is broadcasted from Germany. This device will be used as alarm and is able to show date. There is used display, which consists of 8x32 LED matrix in a modular, which is connected to main board over the edge. This device is controlled by microcontoller PIC16F887A. There are described displays, microcontrollers and DCF time signal.

Digital clock and thermometer with matrix display
Kerndl, Michal ; Stehlík, Jiří (referee) ; Šandera, Josef (advisor)
There is suggestion of obtaining exact time and temperature in this work, based on DCF signal and SMT160 temperature sensor. This project is based on LED matrix display wich is ready-to-connect module. Layout of this work is designed schematic and board layout wich can be used to produce working prototype. This prototype have been created and tested in practice.

Electronic information card
Šafář, Viktor ; Kadlec, Jaroslav (referee) ; Šandera, Josef (advisor)
Tato diplomová práce se zabývá návrhem elektronického informačního štítku, jehož základem je maticový LED displej. V teoretické části jsou probrány použitá rozhraní a periferie mikrokontroléru a PC a diskutuje se nad možnostmi kódování českých znaků. Dále se probírá krok za krokem návrh zařízení. Nejdříve jsou vytyčeny hlavní požadavky a funkcionalita zařízení, následuje výběr vhodných komponent a je navrženo elektrické schéma. Jádrem zařízení je mikrokontrolér Microchip PIC, pro který je dále navržen program. Nakonec je popsána a naprogramována aplikace pro MS Windows, která se se zařízením komunikuje.
