Measurement of greenhouse gas concentrations
Dohnal, Jan ; Vyroubal, Petr (referee) ; Bača, Petr (advisor)
This master thesis deals with the greenhouse effect, various gases and methods of measurement. On the greenhouse effect is viewed from its historical dating, despite changes in atmospheric composition. It contains a theoretical analysis of the individual gases. It focuses on the most harmful greenhouse gases such as water vapor, carbon dioxide, nitrous oxide, methane, ozone, chlorofluorocarbons and halons. Analysis methods for detection of gaseous substances. Part of this work is focus on the detection of nitrogen dioxide, chloro-fluorocarbon and methane. The data is processed using a ATmega’s microcontroller and then sent to an Internet server thingspeak.com. If the device proves successful, will be used as a laboratory exercise in the course Ecology in electronics.

Management of Heating Energy at Home
Dohnal, Stanislav ; Grepl, Jan (referee) ; Kříž, Jiří (advisor)
The aim is to adapt the old heating system so that the new system will meet the needs of users and facilitate control of system. The new heating system can independently control heating automatically. Its important part is remote access to system control. The user always has up-to-date information and can adjust the heating to suit his needs.

Smart Plug
Šebesta, Ondřej ; Szabó, Zoltán (referee) ; Marcoň, Petr (advisor)
The bachelor thesis discusses the design of a smart plug. The theoretical part focuses on the individual parts and functions of smart plugs, and their functional possibilities are analysed together with the related fabrication perspectives. The practical portion concentrates on the selection of appropriate components and proposes a complete design of the hardware and software of a smart plug, including a web server for its control. The practical portion also describes a calibration of a measuring part and compares measured values with values from another measuring device.

Embedded System with Communication Interface NFC and Wi-Fi
Bugár, Loránt ; Valach, Soběslav (referee) ; Horák, Karel (advisor)
This master’s thesis deals with communication system design via the NFC and Wi-Fi interface. The thesis has two basic goals. The first goal is to create a device that is capable of storing of data and its subsequent transfer via the NFC interface. The second aim is to utilize this device for measuring various physical variables. The IoT technology is employed to fulfill the aforementioned goal. IoT technology is capable of visualizing data in real time and make them accessible via the Internet. The result of this work is an universal device, that contains the most popular communication interfaces, such as I2C, SPI and that is capable of processing measurement data from digital, analogue, and wireless sensors.
