Portable Device for Autonomous Meter Reading
Giesl, Vojtěch ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
Bachelor's thesis discusses the design of battery powered devices based on ESP32 module with optical interface, which can be attached to devices, that matching EN62056 standard. First part is focused on theory of Internet of Things, ESP32 chip and EN62056 standard. Next part is focused on designing of prototype device and software for it. Last part is about making designed prototype and programming of web application, which is used for interaction between device and user.
Návrh nízkonákladového řešení regulační a ovládací jednotky pro akvária a terária
PAPAJ, Michal
Bachelor's thesis is focused on a design of a low-cost regulation and control unit for aquariums and terrariums. Initial part examines demands of animals on the environment and possibilities of suitable technologies for aquariums and terrariums. A suitable low-cost technology for the regulation unit is selected. Practical part aims on the design and construction of the control unit system. It is capable of monitoring or regulating, among other things, temperature, pH, water level or lighting. Mobile and web applications are designed and implemented. The system allows a user to oversee the state of the environment and regulate it remotely.
Systém pro řízení chytré domácnosti
This bachelor's thesis addresses the issue of smart home in deployment as an open source system with an emphasis on low budget. In this thesis, three devices are created from scratch, namely a smart thermostatic valve, a power consumption meter and a flood detector. All of them are already deployed. This thesis describes problems in development of own devicecs with testing and comparison with commercial equipment. Among other things, it solves the communication of the local installation of the smart home and the server. In conclusion, it outlined what direction to further the project will develop.
Detection of Subjects Presence in Protected Area
Múdry, Adam ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis was to design and implement a system for detecting the presence of the subject in the protected area using the embedded platform ESP32. The proposed system is able to use several different sensors, allowing the detection of motion, sound, allowing to take photos, etc. The solution was also implemented with the help of the Raspberry Pi platform as a control server and optionally uses cloud services for greater deployment flexibility.
Test Application for Microcontroller ESP32
Šintaj, Oliver ; Jakubík, Mário (referee) ; Dydowicz, Petr (advisor)
The bachelor thesis deals with the analysis and design of a test application for the ESP32 microcontroller for the company ELCOM, spoločnosť s ručením obmedzeným, Prešov (hereinafter referred to as Elcom). The chapter on the theoretical basis of the work describes the necessary information for working with ESP32. The next chapter focuses on the analysis of the current implementation. The last chapter presents the proposal and the form of implementation together with the benefits of the new proposal.
Detached House Computer Network Design
Fabo, David ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
The thesis is focused on designing a computer network in a new family house. The first chapter is focused on analysis of the current state of the object, where the computer network is going to be build. The second chapter is focused on explaining theoretical basis that are related to the issue of designing a computer network. The last chapter is focused on choosing the right parts and putting them together to create a functional computer network.
Smart garden control system
Antoš, Jan ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This bachelor thesis aims to design and implement a distributed control system concept for a smart garden. This system can measure individual physical variables, process the measured data, send it to a central unit and display it to the user. The measured data is then backed up in a database, which is linked to the web for visualisation.
IEEE 802.11 wireless networking for HelenOS
Kolárik, Jan ; Děcký, Martin (advisor) ; Mareš, Martin (referee)
IEEE 802.11 (a.k.a. WiFi) is a popular wireless LAN specification. This thesis documents implementation of this standard within the experimental operating system HelenOS which differs from conventional operating systems with its microkernel-based design. First, the basic concepts of WiFi technology are described. Description of external tools used during development is following. Together with that, the chosen method of integrating the wireless framework into existing system is depicted. In the next chapter we analyse the implementation details of the work. There is thoroughly explained the structure of the driver for selected WiFi device and also the functionality of resulting IEEE 802.11 library. In the end of the thesis there is an evaluation of the features of final work and comparison of enclosed implementation with existing solutions.
Smart Home: Digital Thermostatic Valve Controlled via WiFi
Smejkal, Jan ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
This bachelor thesis deals with smart home heating in households with radiators. The goal is to design a cheap digital heating head and to integrate it via WiFi and MQTT into the Home Assistant system. I have focused on keeping good design, head functions and a good user experience. Home Assistant enables showing graphs using InfluxDB and Grafana. Using a program in tool Node-RED enables it to lower heating temperature at the times of user absence and to schedule heating temperatures. The price of the complete unit is under 400 CZK. Temperature regulation was provided by a prediction controller, but it was replaced by a PID controller. The controller can regulate with the difference of maximal and minimal temperature of around 2 C. The user can control the boost mode of the head via a physical button or using the Home Assistant system. The resulting product is a good basis for a low-cost smart heating system. 
Incubation Chamber with Forced Circulation and Condition Notification
Kadlubcová, Anna ; Čmiel, Vratislav (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with sensors, especially thermometers and hygrometers, the method of measuring and regulating the temperature in the incubation chamber. The main part of the thesis is focused to the design, implementation and testing of the device. The incubation chamber can be tempered to a temperature that can be set in the user interface. Status notification is displayed on the website via WiFi network.
