Control of house heating
Hnyk, Marek ; Šandera, Josef (referee) ; Šteffan, Pavel (advisor)
The aim of the final thesis is a proposal and implementation of a system which would enable a heating control on the basis of data gathered by monitoring of particular rooms inside a building. In particular, it is focused on water measurement within the heating system, TUV (non-potable hot water) and the temperature within the space of residential rooms. The system headquarters must enable an automated saving of the measured data. Selected temperature figures will be made accessible by a web interface and continuously saved on the web server.

Meteo weather station
Dvořák, Jiří ; Fajmon, Petr (referee) ; Fedra, Zbyněk (advisor)
The aim of this master‘s thesis is design and construction of home meteo weather station, the choice of applicable temperature, humidity and pressure sensors and characterization of workable device of station. The core of the station is microcontroller ATmega8 used for process data from sensors. Evaluative criteria for choice of sensors will be comunicate interface, accuracy, operating range, current drain and other aspects. Outer transmittin unit measure air temperature and relative humidity. These data are trasmitted by wireless radio module to interior receiving unit, that measure interior temperature and atmospherical pressure and represent measured data to LCD display including dew point. The data are transmitting to the internet and storing in the database. Measured values are available on the web page where you can display the graphs of last measured values.

Thermography in engineering
Koten, Jakub ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This work deals with non-contact measurement of surface temperatures. The aim of the first part is to explain basic terms, principles and ways of measuring temperature. Furthermore, there is an overview of thermal imagining cameras usable in industry. In the practical part there is a theoretically suggested experiment, which monitors the dependence of the surface temperature on the size of the cross-section of the workpiece during the turning under unchanged cutting conditions. Experimental measurements are executed with using thermocamera ThermaCAM SC 200 and they are evaluated in software called Researcher.

System for measuring of thermal efficiency of solar absorbers
Řiháček, Jan ; Podaný, Kamil (referee) ; Mrňa, Libor (advisor)
The thesis deals with the measurement system for determining the thermal efficiency of the newly developed types of solar absorbers. Measuring equipment allows simultaneous indoor or outdoor thermal efficiency detection of up to four samples absorbers. Emphasis is placed on the flow and heat transfer medium temperature changes. For this purpose is used Biotech FCH-m-POM-LC and LM35DZ sensors. Sensor signal is transferred to a PC using the measuring module NI USB-6221. Here it is further processed by proposed evaluation program. The software is implemented in LabVIEW integrated development environment. In a final part are performed a verification measurements to assess system performance and evaluate the thermal efficiency of various types of solar absorbers. This path is also demonstrated high efficiency applications absorbent layer coating color RABSORB 5.

Wireless sensor for intelligent buildings
Grepl, Tomáš ; Kučera, Pavel (referee) ; Hynčica, Ondřej (advisor)
The theme of the Bachelor’s work is based on the comparison of two measuring schemes measured the temperature for the wireless measurement of the temperature in the building and the comparison of the power consumption of these schemes. Measurement is perforemed by using wireless modules ZigBit900 which are based on ZigBee standard. The first part of the work deals with the theoretical description of the communication standard. There is analyzed the basic issue of technology and the reader can be indicated to the issue. In the second part there is mentioned the description of the developmental kit ZigBit 900. Another section brings the basic information about the programming package BitCloud, which is used for programming of the developmental kit. In addition, designs of two measuring schemes of temperature are mentioned there. Then the reader find there the selection of appropriate application and the part of emended code and the description of temperature measurement. The last chapter schows the measuring and assessing of the temperature. The calculation of the theoretical value of power comsumption for the frequncy band 868 MHz and 2,4 GHz is the lastest researched problem in the work. In conclusion of this Bachelor’s work is included the discussion of achieved results.

Measurement of selected physical quantities
Zajíček, Matouš ; Štěpánek, Vojtěch (referee) ; Pruša, Radomír (advisor)
In the introduction of this thesis a brief literary research of existing types and principles of function of selected sensors of temperature, atmospheric pressure, relative humidity, weight and island electric energy sources is performed. The next part is focused on realization of measuring system, meant for usage on beehive, using Arduino development platform. In the final parts of thesis, a control measurement, verifying function of the system, is performed and energy consumption is evaluated, along with designing a suitable power supply.

Weather Station with Ethernet Interface
Novák, Pavel ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This thesis deals with the design and construction of the meteorological station. The meteorological station is designed and constructed to be able to measure the basic meteorological parameters (temperature, humidity, air pressure) and the other three variables (measuring rainfall, wind speed, wind direction). This thesis will introduce you to meteorology. Meteorology determines the daily weather forecast and the results are used for examples in aviation or maritime affairs. The method of atmospheric origin is given in the theoretical part. Meteorology must use measuring instruments to determine quantities. The dissertation also includes analysis of the measuring instruments. The meteorological station uses the Ethernet technology. In the chapter devoted to Ethernet are described its principles, types and method of power supply over Ethernet. The following section describes the design of the entire meteorological station, selection of all components and description of their connection. The chapter about implementation contains a description of the parts which forms program part of the meteorological station. The aim of the thesis is a summary of the achieved results including price comparison of the renovated meteorological station with other meteorological stations, which can be normally bought.
