Intelligent Presence Detection
Kronika, Vojtěch ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
In this work I dealt with the solution of indoor localization, its design and implementation. We are at a time when the topic of smart home is a daily affair and the solution for indoor localization does not have a certain winner yet. The goal of this work is to create an intelligent presence detector, using Bluetooth technology, which recognizes in which room the device is located. And it estimates in which part of the room the device can be located. To achieve the goal, I use at least three sensors in each room and compare the signal strengths between the sensors and the localized device. A Kalman filter is used for a noise reduction on data signals from sensors. The result of the work is a functional solution for indoor localization. I have found that it is not easy to use rapidly changing signal strength within triangulation to obtain the exact position of the device. Further work could address what needs to be done to make triangulation possible and functional. One of possible directions is an exploration of Bluetooth Direction Finding technology.

Control system for drip irrigation
Zíka, Radim ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The bachelor thesis deals with designing drip irrigation control system. Aim of this thesis is realisation of microcontroler system which enables scheduled control of multiple branches of drip irrigation in an orchard. The design is focused on keeping the power consumption of the circuitry as low as possible. Theoretical part of this thesis focuses on research on drip irrigation and on low power circuit design theory. Practical part of thesis covers microcontroler system design, schematic design, printed circuit board design, revival of designed PCB and designing its control software.

Data concentrator
Dvorský, Petr ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
The topic of this thesis is the design and realization of a modular Data concentrator for various types of measurements in diverse conditions. The device conception, basic principles, design and functionality are described herein. Also, the lightweight protocol design for radio communication, standardized XML format for data storage and cloud usage are described. The electrical design of the device as well as the design of the printed circuit board was made using the Eagle Autodesk electronic design automation software (Eagle Autodesk EDA). The control software written in C/C++ for a target microcontroller (ESP32-WROOM-32) is based on a FreeRTOS platform and ESP-IDF framework. An IDE for managing this software is Visual Studio Code with PlatformIO extension. Selected and used Cloud Platform is ThingSpeak from Mathworks, which uses certain components from Matlab platform.

Control Unit with (Espressif) ESP32 Module
Smička, Daniel ; Krejčí, Jan (referee) ; Škorpil, Vladislav (advisor)
This bachelor thesis describes concept, design and making of control unit with module Espressif ESP32. At first we apply to proposition of theoretical communication blocking scheme and blocking scheme of design. Afterwards we apply to designing of the scheme and choosing appropriate parts and making design of printed circuit board. In the end we are going to code function of the module and we will make end-user device.

Power outage simulator
Sýkora, Dušan ; Lieskovan, Tomáš (referee) ; Kohout, David (advisor)
This thesis is concerned with building a smart gadget that is able to simulate blackouts. This simulator is able to interrupt or limit supply of 230 V electricity from a power grid to the tested appliance for adjustable duration and with adjustable frequency. The gadget is controllable remotely via a web interface. For that purpose, components have been selected and a program written for a microcontroller. Finally, functionality has been verified on multiple appliances.
