Asynchronous MQTT Client Library for Embedded Devices Running on Drogue-IoT Firmware
Babec, Ondřej ; Lichtner, Ondrej (referee) ; Pluskal, Jan (advisor)
IoT je odvětví informatiky, které v posledních letech masivně expanduje. V dnešním světě je IoT všude kolem nás. Jsou to chytré žárovky a doplňky do domácnosti, ale také tisíce zařízení v průmyslových objektech. Nedílnou součástí IoT jsou protokoly pro zasílání zpráv, které umožňují komunikaci komunikaci s těmito zařízeními. Dnes již existuje mnoho projektů, které umoňují integraci IoT zařízení a následné cloudové zpracování jejich zpráv. Jedním z těchto projektů je Drogue-IoT. Tento open-source projekt umožňuje vytvářet firemní cloudové řešení, ale také firmware pro vestavné zařízení. Jednou z limitací tohoto projektu je nepřítomnost klientské aplikace podporující zasílání zpráv pomocí protokolu MQTT. Právě tato klientská aplikace je tématem této práce. Práce zahrnuje návrh a implementaci klienta protokolu MQTT pro vestavěná zařízení v jazyce Rust, který doposud neexistuje. Řešení je demonstrováno pomocí sestrojeného zařízení. Výsledná práce vyhodnocuje implementaci klienta a obsahuje návrhy na budoucí vylepšení práce.

Intelligent LED Light
Krejčí, Martin ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
The aim of the bachelor thesis is to design and implement a prototype of intelligent LED lighting with the possibility of mixing cold white, warm white, red, green and blue colours. To create communication, control units including a W(LAN) unit that will allow communication outside this closed bus. This thesis is the first to describe light and its history. The design of the device itself consists of a 3D model of a prototype LED light embedded in the ceiling, followed by the selection of the specific circuits used. In the design, the shortcomings of today’s smart wiring systems were taken into account. The thesis concludes with a description of the hand-fitting of the circuit boards and the measurement results of the designed LED exciters.

Intelligent LED Light
Krejčí, Martin ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
The aim of the bachelor thesis is to design and implement a prototype of intelligent LED lighting with the possibility of mixing colours (cold white, warm white, red, green and blue) and with integrated motion, smoke, temperature and pressure sensors, which can be connected to an island photovoltaic system. Create a control unit and a W(LAN) unit that will allow communication outside this closed bus using a web interface. Establish appropriate and reliable communication between all proposed system units. The thesis first describes lighting, its history and the use of multi-colour LED lighting today. Then all the buses used are described. The design of the device itself consists of a 3D model of the prototype LED lighting embedded in the ceiling, followed by the selection of the specific integrated circuits, microcontroller kits and other peripherals needed. At the end of the paper, the measurement results of all the designed components of the device are summarized.

Secure Bootloader For Arm Microcontrollers
Prítel, Pavol
Embedded systems are single purpose devices, where software updates are often omitted or very limited in comparison with personal computer systems. Such systems are typically using microcontrollers with limited memory and computing power. Enabling software updates on an embedded system brings some security issues that need to be taken into account. As soon as there is a possibility of software update, the device is exposed to risk of malicious or not original applications being executed on the device. In this paper a reference implementation of bootloader with security features is described. As a result of using asymmetric cryptography, the memory footprint and startup time is increased significantly. The contribution of this work is in finding the right algorithm that will offer trade-off between level of security and used resources of targeted microcontroller.

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

Implementation of Deep Learning Algorithm on Embedded Device
Ondrášek, David ; Boštík, Ondřej (referee) ; Horák, Karel (advisor)
This thesis deals with the implementation of inference model, based on the methods of deep learning, on embedded device. First, machine learning and deep learning methods are researched with emphasis on state-of-the-art techniques. Next, the best suitable hardware had to be selected. In the conclusion, two devices are chosen: Jetson Nano and Raspberry Pi. Then the custom dataset, consisting of three classes of candies, was created and used for training custom inference model through the transfer learning technique. Model is later used in the application, capable of object detection. Application is implemented on Jetson Nano and Raspberry Pi and then evaluated.
