Wireless sensor of temperature and relative humidity
Chlad, Miloslav ; Jaroš, David (referee) ; Macháň, Ladislav (advisor)
Bachelor thesis deals in general with humidity and possibility of its measurement. As are psychometric method, hygrometric method and dew point method. The next chapter is an overview of sensors available on the Czech market, along with a brief description of their attributes. Furthermore, the thesis deals with hardware and software design of wireless temperature and relative humidity measuring unit.

Remotely controlled thermostat
Závodný, Vilém ; Hanák, Pavel (referee) ; Šteffan, Pavel (advisor)
The aim of my thesis is to understand the manufactured thermostats and design own thermostat to allow the most basic possibilities classical thermostats plus setup and management via web interface. It is a realization of a small web server that works closely with hardware peripherals. In addition, the web interface is still possible to manage a Web server of TFT LCD screen or applications for smart phone with Android. In addition, the thermostat allows the temperature reading from the BLE modules. All temperatures are continuously stored in a database and graphically processed.

Analysis of methods used for measurement of moisture in building materials
Hrabálková, Eliška ; Žák,, Antonín (referee) ; Šťastník, Stanislav (advisor)
The diploma thesis is focused on the issue of measuring the moisture content in building materials using indirect methods that allow its long-term measurement. The theoretical part of the thesis provides an overview of the forms of moisture in porous building materials and provide an overview of the principles of measuring moisture content. In the experimental part of the thesis, the aim is to verify the available methods for long-term monitoring of moisture in building materials built into building structures. Proven methods of measuring humidity include resistance, capacitive and microwave methods and their comparison with the results of gravimetric measurements. At the end of the work is an evaluation of knowledge and recommendations for further research in this area.

Temperature, pressure and humidity monitoring system for a workshop floor
Kudera, Tomáš ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
This thesis deals with the design of overall concept of distributed system which is used for temperature, pressure and humidity measurement. The system is adapted to be used in instrument transformers and sensors production hall of ABB s.r.o. Brno. Firstly, the requirements for the measuring system are defined. After that market research focused on sensors and measurement modules is performed. The selected sensor is afterwards built into own measurement module for which hardware and software part is designed. The work continues with design of local and remote database of measured values. Besides, the PC software used for local and remote data storage is designed afterwards. The components of the measurement system are tested in the final part of the thesis.

Analysis of indoor climate of spa resort
Chadima, Tomáš ; Rubinová, Olga (referee) ; Horká, Lucie (advisor)
The thesis deals with the environmental assessment of buildings, concrete objects Letní lázně at Karlova Studánka. The first part describes the issue and legislation. There is also described a method of experimental measurement and methods of moisture measurement. The second part deals with the analysis of the specified object, description of selected renewable sources and description of possible modifications of the object. The third part is devoted to modeling and simulation of the specified object in DesignBuilder. Using the model were created various simulations with various modifications in order to reduce energy intensity of the object. Results were then evaluated and compared.

Assessment of thermal comfort in buildings
Procházka, Aleš ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This bachelor thesis summarises knowleges about methods used for assessments of thermal comfort in buldings. In opening part of thesis is thermal comfort introduces as important part of overall satisfaction with indoor environment. There are also described fyziological basics and ways of thermoregulation and individual elements of thermal balance. Next part of thesis is focused on thermal and humidity factors of indoor environment. Some combinations of these factors form thermal comfort. Main part of thesis describes methods of assesments of thermal comfort using PMV and PPD indices. For practical uses there are examples of comfort diagrams, which are based on PMV index, Thermal Comfort Meter and Thermal Manikin. Last part contains description of some instruments for measurement of used physical values.

Weight sensing of beehives with IoT connectivity
Havránek, Daniel ; Frýza, Tomáš (referee) ; Kufa, Jan (advisor)
The purpose of this work is to make a device that can measure some beehive parameters, that can inform you about the conditions in a beehive. These parameters are beehive weight, inner and ambient temperature, inner and ambient humidity and air pressure. The device allows to send the measured data wirelessly through the 2G network and interpret the results in appropriate way. Low power consumption is desirable due to working without the reach of the distribution network.

Arduino programming with Matlab/Simulink
Bartoněk, Jan ; Hůlka, Tomáš (referee) ; Matoušek, Radomil (advisor)
The content of this bachelor´s thesis is a research of possibility of programming an Arduino microcontroller using Matlab/Simulink program. Part of the thesis is also a brief research of the Arduino platform. Furthermore, two practical tasks were created and described in this work, which can be used for educational purposes. The first being an application demonstrating the use of the DHT22 sensor, created using App Designer, which is part a of Matlab. The second task deals with the regulation of the position of a levitating body in the tube, using Simulink. Demonstration videos were created for both tasks and are part of this work.
