Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

From a Dumb Boiler to a Smart One Using a Smart Socket
Mitura, Jacek ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
Nowadays, the world of smart devices is growing very fast. Nevertheless, it remains difficult to acquire smart device for water heating applications. The usual reasons complicating this fact include the lack of the possibility of connection to the central control unit, or the need to replace the entire boiler with a new smart model. In both cases, the additional disadvantage is the higher price of such a solution. Therefore, the aim of this bachelor's thesis is to create a comprehensive and affordable solution, ensuring the conversion of an existing boiler to smart using a smart socket and a central server controlling the household. The solution uses a daily consumption forecast based on an exponential moving average to save electricity.

Automation and Accounting of Coffee Machine
Víšek, Jakub ; Ryšavý, Ondřej (referee) ; Pluskal, Jan (advisor)
The goal of this thesis is to design and implement an embedded and information system for automatic accounting of coffee dispensed by a vending machine. Features of the created solution include reliability and portability. The system can be easily extended for use in point of sale applications different to coffee machines. The results enable easy deployment of electronic accounting of purchased products and demonstrate integration of a microcontroller which controls a coffee vending machine on the basis of identifying users by their RFID tags.

Educational board for STM processors
Očenášek, Matěj ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This work deals with design of educational board for STM32 microcontrollers. This educational board contains basic types of peripherals such as OLED display, EEPROM, LED or seven segment displays. The theoretical part focuses on the description of the STM32F303 processor and the Nucleo-64 development board on which the processor is installed. It describes in particular its properties. In the theoretical part, besides the STM32F303 processor, the individual parts of the educational board are described. The practical part deals with the design of the block diagram, the scheme and the design of the printed circuit board.

Smart Home Solution Based on ESP Modules and Raspberry Pi
Bartoš, Martin ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
Nowadays, the world of smart devices in households is growing significantly, where the devices communicate with each other and make people's lives easier. However, a major problem with the purchase of these devices to common households is the high price and compatibility of those products from one vendor. The goal of this bachelor thesis is to create a comprehensive low-cost smart home solution that the user will be able to manage without much effort. This solution is implemented by the latest technologies and tools.

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.

Home Automation Based on Arduino/WeMos/RPi Platform
Bubeníček, Daniel ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
This thesis deals with design and implementation of home automation system based on Arduino, WeMos and Raspberry Pi platforms. Twelve modules for home automation were designed, which can be easily built on these platforms. The implemented prototype allows to control heating system and LED light, track temperature and humidity, detect newly connected Wi-Fi devices, human motion, door opening, create custom automation rules etc. The system uses pre-existing household equipment. The new hardware used in prototype cost only 1.600 CZK.

Security Analysis of Home IoT Network
Čikel, Tomáš ; Jeřábek, Kamil (referee) ; Pluskal, Jan (advisor)
This work focuses on the issue of the security in home IoT network. Specifically, it focuses on the security issues of commercial IoT devices and their automation systems. In the work itself, it was firstly analyzed and identified specific threats specific for our network. To address these threats, the original automation systems and firmware on the devices were replaced by open-source implementations that were configured to address discovered threats. Although, there are still several security issues in a network with an open-source implementation, a large part of the security issues which were discovered has been eliminated. The results of this work allows to configure a home IoT network using an opens-source automation system and firmware and proves that such a network is more secure than the network where the original factory-supplied automation systems and firmware on devices are used.
