IoT system for gardening
Mlčák, Petr ; Kiac, Martin (referee) ; Caha, Tomáš (advisor)
The thesis deals with the design and creation of a weather station suitable for gardeners. The created device is able to measure temperature, pressure, humidity, amount of precipitation, wind speed and direction, UV index and also temperature and soil moisture at several depths. The weather station is powered by a battery with auxiliary charging from a photovoltaic panel. The thesis is divided into several parts. The theoretical part describes the individual physical principles of measurement of the considered physical quantities. Subsequently, a comparison of available sensors is made and then a final selection is made. The third part deals with the design and implementation of the hardware circuitry including the creation of the PCB. In this section, the holders of each sensor are also designed for printing on a 3D printer, which are then printed. The fourth section deals with software design issues, which is described in more detail. Finally, the whole weather station is assembled, wired and the functionality of all components is verified by sending the measured data to Thingspeak.

Intelligent beekeeping system
Hrubý, Jan ; Zeman, Václav (referee) ; Kiac, Martin (advisor)
The aim of this thesis is to design and develop an intelligent beekeeping system that can measure the frequency in the colony, the weight of the hive to monitor the loss or to inform the beekeeper if the bees are carrying honey. Furthermore, the security of the hive against theft is also being considered. Communication between multiple intelligent beekeeping systems is important for the functionality. This is why part of the work focuses on choosing the best possible communication, taking into consideration battery consumption and reliability. In this work, a many-to-one communication system of modules is used, which means that the number of hives can be freely expanded without affecting the functionality of the system. The resulting system is powered by a combination of battery and solar panels.

Black-Box Analysis of Wi-Fi Stacks Security
Venger, Adam ; Orsák, Michal (referee) ; Malinka, Kamil (advisor)
Zariadenia, na ktoré sa každodenne spoliehame, sú stále zložitejšie a využívajú zložitejšie protokoly. Jedným z týchto protokolov je Wi-Fi. S rastúcou zložitosťou sa zvyšuje aj potenciál pre implementačné chyby. Táto práca skúma Wi-Fi protokol a použitie fuzz testingu pre generovanie semi-validných vstupov, ktoré by mohli odhaliť zraniteľné miesta v zariadeniach. Špeciálna pozornosť bola venovaná testovaniu Wi-Fi v systéme ESP32 a ESP32-S2. Výsledkom práce je fuzzer vhodný pre testovanie akéhokoľvek Wi-Fi zariadenia, monitorovací nástroj špeciálne pre ESP32 a sada testovacích programov pre ESP32. Nástroj neodhalil žiadne potenciálne zraniteľnosti.

IoT Home System
Kovařík, Viktor ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
The aim of this thesis was to learn and summarize basic information about IoT systems, which protocols are used and introduction of Google Home system. The first part of the thesis describes the individual parts of the system --- microcontrollers, sensors, light elements and possible systems for backend. In the implementation part of the thesis was designed a solution for smart home controling using Google Home technology. Based on data from the weather station, the system controls and adjusts the intensity of outdoor lighting and controls the blinds. Furthermore, a control module for gate and garage door control is implemented. The system also takes care of vacuum cleaning in the house using iRobot Roomba vacuum cleaners with custom Wi-Fi module. The final part of the thesis summarizes the achieved results.

Flow measurement in microfluidic systems with recording and sharing of measured values
Duša, Martin ; Harabiš, Vratislav (referee) ; Čmiel, Vratislav (advisor)
This paper is focused on flow measurement, microfluidic systems and realization system, which is able to flow measure and share with the possibility of their visualization via web interface. The first part of the work is devoted to the theoretical research, which briefly deals with the theory of flow and other concepts that belong to the flow There are also mentioned principles of flowmeter and their advantages or applications. The second part is devoted to microfluidic system. This section describes the elements that make up the microfluidic system, their capabilities and applications. The last part is devoted to the realization of the measuring system. The implementation includes a design of the measuring system, where the selection of microcotroler and sensor is given. The software solution includes used platforms and examples of algorithmization. At the end, the physical implementation of the whole system and calibration is described.

Control system for air monitoring
Chlumecký, Karel ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
The master’s thesis focuses on the development of household device which allows the user not only to measure quality and properties of air in individual rooms but also allows graphical display of measured values via wireless transmission. The work first deals with selection of a suitable microcontroller and then the wireless communications and used peripherals are briefly described. Furthemore, the work deals with the design of the device itself, its hardware and software equipment, as well as its construction. The financial costs are also analyzed in this work. Part of the work is the final testing of the completed equipment for measuring in two rooms of a residential house.

Wireless Communication for Home Automation
Sezima, Václav ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
This bachelor's thesis deals with the issue of wireless communication among devices and sensors for home automation. The goal is to design and implement a device known as the gateway that is passing messages and commands between sensors and controller that controls them from central point, e.g. computer or mobile phone. A part of this thesis is also a creation of several sensors for the purpose of testing and demonstration. The gateway and sensors are based on development boards WEMOS and Arduino and supports multiple wireless technologies for communication with among themselves and controller.
