Smart Home System
Hájek, Jaroslav ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This work deals with connecting remote devices measure data of various types from physical quantities such as a temperature, a humidity to data displaying CPU or memory usage of the system to the user. The system uses Blockly to controlling logic and dependencies between devices. In the work is used lots of technologies for examples: MQTT, Websockets, GSM, Lightweight Mesh and others. The system is based on microservice which named is Flask. Flask service is an application interface for HTTP services of Python programming language. This can provide measured data by graphs and predefined components for viewing data. For controlling system was used single-board computer Raspberry Pi with a multitouch 7-inch display.

Development kit for microcontrollers communication with computer
Franek, Miroslav ; Novák, Lukáš (referee) ; Levek, Vladimír (advisor)
Master’s thesis deals with the design of development kit for communication between a microcontroller and a computer using USB, Bluetooth, WiFi and Ethernet interfaces. In the theoretical introduction is the analysis of theese interfaces and the interfaces used for communication by the microcontroller. In the next part, components for the development kit are selected. Then a wiring diagram and the printed circuit board is designed. Next, the firmware design is described. The last chapter deals with the implementation and testing of the development kit. The appendix contains a proposal for a laboratory task to introduce the development kit to students.

Distributed Control System with Dynamically Evolvable Nodes
Křek, Radim ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This thesis describes creation of dynamically evolvable node, which will cooperate with other nodes. Group of these nodes will then create a distributed control system. The MQTT protocol is used for communications purposes between individual nodes. As hardware platform is used ESP32 and ESP8266. Whole operating system is written in MicroPython and supports a live uploading of user applications written in the same language. Later in thesis is decribed creation of monitoring node on Raspberry Pi, which control network. Complete system can be then used to control a intelligent 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.

Reconfigurable ESP8266/ESP32-Based Node for IoT
Drahovský, Peter ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
The purpose of this thesis is to create reconfigurable system for microcontrolers ESP8266 and ESP32 with usage of interpreted language. System enables to load and run aplications, which are allowed to comunicate with other aplications that are running on any of the nodes on the same network. A protocol used to communicate within aplications and the system is compatible with one used in PNOS (operating sysem based on Petri nets). System can cooperate with PNOS on the same network, or it can be run on its own.

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.

Low-energy Security Device with (Espressif) ESP8266/ESP32 Module
Ondráček, Petr ; Lattenberg, Ivo (referee) ; Škorpil, Vladislav (advisor)
Bachelor's thesis discusses the design and realization of low-energy security device using Wifi module ESP32. The device will detect the opening of door/window/space by using magnetic contact and this event will be reported on appropriate cloud service and by e-mail. The theoretical part is focused on the Internet of Things problematics, cloud services and description of individual components of the final device. Second part of thesis is focused on designing of the linkage scheme, control program and calculation of power consumption of the device. Third part is already focused on practical realization of the designed device, designing and creation of printed circuit board and security box, programming, creation of the cloud channel that will visualize collected data and measurement of power consumption of the final device.

Temperature Sensor Using (Espressif) ESP32 Module
Roško, Tomáš ; Lattenberg, Ivo (referee) ; Škorpil, Vladislav (advisor)
This bachelor thesis focuses on construction of battery powered temperature sensor with Wi-Fi module ESP32 with the possibility of connection to any analogue industrial sensor. The construction of module emphasizes on minimal battery power consumption with taking into account the longest possible duration per one charging battery cycle. It is also stressed on the way of storing measured data and realization of website, which presents those data to the end user in a comfortable manner. The theoretical part describes Internet of Things, accentuates its history, usage and security. The chapter also covers vast possibilities of application of different sensors and their usage in both industry and ordinary life. The Internet of Things chapter is concluded with description of most used communication technologies and protocols. The practical part is concerned with construction of temperature sensor with ESP32 module. It is divided into three main parts. First part deals with the specification of requirements and the design of the device. It also takes into account the choice of best possible way of powering the device by battery and calculation of battery life. Chapter also discusses individual parts of the whole device, such as the choice of temperature sensor or the solution of connectability of industrial sensors. The second practical chapter deals with the realization of device, both in hardware and software way. Hardware part describes realization of the printed circuit board and its 3D printed coverage, whereas software part sheds light on the programming of the device and how the web presentation works. The final chapter presents two main things: how was the module tested and complete financial calculation for the whole project.

Sensors for driver assistance systems
Ptáček, Martin ; Čala, Martin (referee) ; Beneš, Petr (advisor)
This bachelor thesis is devoted to vehicle stabilization systems, especially to the Anti-lock Braking System ABS, Anti-Skid Regulation ASR and Electronic Stability Program ESP. The main emphasis is placed on sensors needed for implementation of these systems and their required parameters. Findings learned are applied for the implementation of the stabilization system in the model car of the scale 1:10. The relation between the quality of measured sensor data and quality of the resulting stabilization is analyzed using model platfrom testing.
