The Sport Activity Digital Recorder
Raninec, Michal ; Žák, Jaromír (referee) ; Macháň, Ladislav (advisor)
This paper discuss the design of multifunctional device used as the digital recorder for sport activity. The general aim is to explore theory issues, construct the device and develope software for the application. Components were chosen considering low weight and power consumption and with as accurate tracking as possible.

Simple FITkit Based Weather-Station
Podivínský, Jakub ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
In this bachelor thesis, the design and implementation of FITkit-based home weather-station is presented. In the thesis, various methods of measuring meteorological quantities are detailed and discussed together with advanteges and disadvantages of common electronic sensor parameters. Then, weather forecast methods are classified and principle of a simple weather-forecast algorithm based on the atmospheric pressure measurement and analysis is described and discussed according to its realization by the means of the FITkit platform. At the end of the thesis, design and realization of an additional hardware needed to operate the station on basis of FITkit is described.

Weather measurement
Chovanec, Jan ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
The achievement of this thesis is to design functional equipment which is able to measure the basic meteorological variables as air temperature, humidity and barometric pressure. In order to measure relative humidity completed with temperature, an intelligent sensor manufactured by Intersema Inc., MS5534B, was chosen. Relative humidity is measured by a capacitance sensor Humirel HS1101LF. The measured data are stored in anon-volatile memory. Data can be downloaded to a computer file via serial port or they can be online displayed on the computer screen via the wireless Bluetooth connection. Because the equipment is supposed to be used for the external measurement without the connection to electricity, low power consumption was considered as a most important parameter as well as good weather protection.

Electronic instrument for environment monitoring during plants growing
Žák, Jaromír ; Kuchta, Radek (referee) ; Hubálek, Jaromír (advisor)
The main goal of this project is to make electronic instrument for monitoring environment during plants growing for Mendel University of Agriculture and Forestry in Brno. The new device will replace current analog recorder of temperature and humidity. New device will be extended by measuring atmospheric pressure, illumination and CO2 concentration. Main advantage of electronic measuring is better lucidity of gained values. New concept allows easier comparison new values with earlier measured data.

Impacts of climate changes on milk production efficiency in dairy cattle during a calendar year
UHEROVÁ, Jaroslava
Negative effects of high temperatures on cattle milk production is a specific problem. Dairy-cows, who produce much more heat than cows that are not milked, are more susceptible to high temperatures of the surrounding environment than other cattle. Changes in temperatures and atmospheric pressure were monitored throughout a year and then its influence on the milk production of cattle has been evaluated. It has been discovered that low temperatures do not have any significant influence on dairy-cows. However, at high temperatures dairy-cows suffer from heat stress and it leads to lower volumes of the daily milk production. The Holstein breed showed a higher sensitivity to temperature fluctuations than the Czech spotted breed; however, the Holstein breed milk production is better balanced in a long run (a year period).

Application versatile module LabJack\hindex{TM} in education of physics
PŘIBYL, Vojtěch
Theme of this thesis is using of universal module LabJack U3-HVTM as support for physics lessons. This thesis describes the universal module LabJack U3-HVTM and evaluation method of measured value on the computer screen using software eSimLab. To all physical tasks is described path of signal with measured string from developed sensor until evaluation of signal in the computer. In the thesis is specifically described a function of developed sensors of physical quantities, there are subscribed diagrams including PCB and parts list. The thesis is including designed physical tasks for monitoring of atmospheric pressure, temperature, wind direction, sunshine duration and the role of measurement of the signal on the optical transmitter using the developed sensors and universal module LabJack U3-HVTM.
