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.

Monitoring equipment for fermentation processes using the thermodynamic sensors
Jáneš, Pavel ; Búran, Martin (referee) ; Adámek, Martin (advisor)
The bachelor's thesis is focused on the design and implementation of a prototype device that is to be used to monitor fermentation processes in the food industry using thermodynamic sensors. The work contains a brief description of fermentation processes in the food industry and also possible methods of their monitoring. It also deals with the principle of the thermodynamic sensor and the description of the ESP32 microcontroller, which is the core of the prototype. Subsequently, it deals with the design of a prototype, including a program for ESP32, which is able to monitor the fermentation process using a pair of thermodynamic sensors and send the measured data to the cloud service ThingSpeak, to a personal computer or store them in Flash memory. Furthermore, the work deals with testing in experimental measurements, in which fermentation processes were monitored with the prototype.

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.

Room Presence Detection in the Smart Home
Průdek, David ; Letavay, Viliam (referee) ; Pluskal, Jan (advisor)
The purpose of this thesis is to design and implement presence detection sensor which works with home automation. I focused on sensor implementation which needs for activity only available wearable electronics. Sensor placed in room can detect other devices and based on signal intensity it determines his location. For this case I chose Bletooth LE which is used to be implemented in the most of wearable electronics and recently new utilization of BLE was found for indoor navigation. Using this sensor for automation is ensured by system Home Assistant. Main benefit of this project is simply and cheap extend home automation capabilities for person detection in rooms, not only detection in large areas which offers GPS and Wi-Fi systems.

IoT WiFi soil moisture and temperature sensor
Kostelanská, Alžbeta ; Zeman, Václav (referee) ; Škorpil, Vladislav (advisor)
Bachelor thesis addresses the subject of IoT WiFi soil moisture sensor and temperature sensor based on ESP32 platform. The primary focus of the design is on low power consumption of the device and secure communication. The theoretical part of the thesis describes selected types of sensors which can be used for the designed device. The ESP32 module and some of its features are also introduced. Lastly selected communication protocols which are suitable for IoT applications and can be used with WiFi peripheral are discussed. The practical part of the bachelor thesis deals with hardware design of the sensor device and implementation of this design. Low power consumption is implemented in hardware and in software solution. The focus is on independence of the device and secure communication and data protection. Lastly the concept of webserver used for storing and processing collected data on RaspberryPi platform and concept of sending the measured data to the end-user are introduced.

Návrh automatizované vyhřívané pece pro testování FDM výtisků
Kodýtek, Jan
This bachelor thesis deals with the analysis, design, construction and optimization of a special furnace for heat treatment and testing of products manufactured by additive 3D printing technology. The first part of the thesis deals with a literature search of currently available industrial and DYI solutions. Based on the conducted research, a custom solution is proposed based on DIY (Do It Yourself) reflow oven projects, which are mainly used in the electronics sector for industrial soldering of components. The control of the furnace is implemented using ESP32 microcontroller and FreeRTOS operating system. All the necessary mechanical components were modelled in SolidWorks software and then manufactured either by 3D printing or conventional machining methods. The work also includes an oven control system that runs on the mentioned microcontroller, runing in access point mode and can therefore be remotely connected to it. The described control system also allows for the creation of custom predefined temperature profiles that can be reused. The proposed solution was subsequently tested with satisfactory results.

System for Transmitting Diagnostic Data from the Car
Uhliar, Martin ; Vašíček, Zdeněk (referee) ; Goldmann, Tomáš (advisor)
This diploma thesis deals with the design and implementation at the software and hardware level of the device, which is used for communication and acquisition of diagnostic data from the car control unit. The acquired data can be stored on the device and also sent via LoRa technology and TheThingsNetwork to a database on a remote server. NB-IoT technology is used for data that needs to be obtained in real time. The recorded data is presented in the form of a mobile application, which displays the obtained data to the user and can notify him of a problem with the vehicle. The device communicates with the car via the CAN bus using the OBD2 protocol and is controlled by an ARM microcontroller.
