Electronic chess
Kočka, Matúš ; Arm, Jakub (referee) ; Baštán, Ondřej (advisor)
This bachelor thesis is focused on function of capacitive sensors on a printed circuit board and a series of measurements from which it was possible to create a subsequent sensors for the chess board. It also deals with the CoreXY technique, according to which a design of a motion mechanism is made in the Siemens NX program, and its subsequent implementation. The device includes a microcontroller for which software is created to process data from sensors and control stepper motors.

Measuring station with data transmission via LoRa network
Nguyen, David ; Formánek, Martin (referee) ; Najman, Jan (advisor)
This thesis deals with the data transmission from the measuring station via LoRa network. The goal is to research possible solutions of data transmission using a LoRa technology and to select suitable hardware for creating a measuring station. Subsequently, setting up radio module with sensors and developing web application that will collect, store and present the data from the measuring station. This thesis includes tests of power consumption, range and transmission reliability of the end node.

Coordination of MicroPython-Based IoT by Means of Node-RED
Kolář, Josef ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The target of this thesis is to create means for using the Node-RED tool to coordinate physical nodes in the form of ESP32 chips in the Internet of Things. This is fulfilled by created Node-RED extension, the proposed MQTT channel protocol and custom firmware for these nodes. All of this suport deploy of diverse applications to nodes simultaneously side by side. The designed and implemented MicroPython firmware is capable of asynchronous operation of individual applications which provides an interface to communicate with the Node-RED. The functionality of this system has been successfully validated on the basis of two practical usage scenarios that demonstrate the possibility of direct use deployment system into practice in automation - even with the included firmware installer.

Guarding and Securing of Objects and Areas Based on Arduino/Sigfox
Sadílek, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design and build a~guarding system using Internet of Things communication protocol. The system is based on the Arduino Nano developement board, the Sigfox communication module, and security sensors. The measured data are sent to the server, processed, evaluated and stored in MySQL database. When the alarm is triggered, the user is notified. The information is accessible to users on the web server.

Environmental monitoring with the FLIR Lepton miniature thermal camera
Niedoba, Marek ; Adámek, Roman (referee) ; Najman, Jan (advisor)
Tato práce se zabývá monitorováním prostředí použitím cenově dostupného teplotního senzoru s vývojovou platformou. První část prezentuje základní přehled o termovizní technologii a jejím využití. Dále se zabývá technickými specifikacemi a funkcemi senzoru Flir LEPTON 3.5, a vývojové platformy OpenMV Cam H7 R2. Druhá část práce poskytuje informace a instrukce ohledně práce se senzorem a ukazuje některé možné aplikace. Také jsou zde ukázané způsoby jak překonat některé limitace senzoru a porovnání s jinými komerčně dostupnými termokamerami.

Supervision and Control System for a Hotel Implemented by IoT Means
Hockicko, Matej ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
This work solves the design and prototype implementation of supervision and control system for a hotel implemented by IoT means. The solution is based on ESP microcontrollers, which control the connected sensors and actuators. ESP devices are futher grouped and connected to central point within range. Using this point, MQTT communication is futher transmitted to the cloud. The cloud runs the IoT Core service, which allows to control and store the status of devices. There is also a Node-RED developmnet tool, in which a graphical interface was created for this system. The result of this work allows remote monitoring and control of the hotel using sensors and actuators connected to this network.

Dynamic Mesh Network Implemented in Micropython on Top of ESP-NOW Protocol
Šesták, Jindřich ; Hujňák, Ondřej (referee) ; Malinka, Kamil (advisor)
Cílem této práce je vytvořit fungující dynamickou mesh síť na ESP32 microkontrolerech pro využití v IoT a senzorových sítích. Mesh síť se skládá z několika uzlů mezi sebou propojených do stromové struktury a je schopna se vypořádat i z pádem kteréholiv z uzlů. To je zajištěno vytvořením nového mesh řešení, které je schopno fungovat s připojením k Internetu i bez připojení. Použití MicroPython umožňuje asynchronní zpracování neblokujícím způsobem. Projekt je postaven pomocí dvou komunikačních protokolů, proprietárního ESP-NOW a běžné WiFi komunikace. Řešení přináší možnosti rychlého vývoje mesh aplikací, ale je silně limitováno pamětí mikrokontrolerů. Funkčnost řešení byla otestovaná pomocí vytvořené demo aplikace se sadou třech testovacích scénářů pro domácí použití.

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.

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.

IoT with Reconfigurable Nodes in Python
Pitko, Erik ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
The main goal of this thesis is creation and implementation of monitoring software for reconfigurable ESP32 nodes equipped with the existing operating system MPOS. This system is then used to solve specific task. The monitoring system is capable of loading, activating and maintaining applications written in MicroPython language that is running on these nodes. Nodes can communicate with other applications using the MQTT broker.
