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.

Weather station with air quality measurement
Lacina, Jaroslav ; Hájek, Jaroslav (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with the design and implementation of the wireless weather station with air quality measurement. At the beginning of the theoretical part, meteorology will be analysed. Afterwards, this work describes physical principles and the method of measurement of physical quantities that are measured by the meteostation. Next is the folloving technology described - Internet of things. The weather station is powered by a single battery and operates autonomously without any user intervention. It measures temperature, humidity, atmospheric pressure, CO2 and tVOC. Measured data are saved in to the cloud service ThingSpeak using a GSM signal. Further the work focuses on creation of web applications. The well organized graphs are created from the measured values.

Collection of meteorological data using the MQTT protocol
Filippov, Andrii ; Šilhavý, Pavel (referee) ; Lattenberg, Ivo (advisor)
Cílem této práce je sběr meteorologických dat pomocí protokolu MQTT ze dvouvytvořených meteorologických stanic založených na mikrokontrolérech typu ESP32 a ESP8266. Práce pojednává o textovému formátu JSON, jeho struktuře podle řady kritérií a jeho dalšímu využití při přenosu dat z meteorologické stanice. Další fází je studium a srovnání hlavních charakteristik mikrokontrolérů ESP32 a ESP8266. Na základě zadání byly pak vytvořeny autonomní meteorologické stanice. Dále byly porovnány existující MQTTservery pro sběr, ukládání a přenos meteorologických dat mezi klientem a serverem. Závěrečnou fází práce byla tvorba programu v jazyce C#, který generuje grafy na základě hodnot aktuální teploty a relativní vlhkosti přijatých ze serveru MQTT. Výzkumný projekt se skládá ze dvou autonomních meteorologických stanic, ze kterých jsou přenášena meteorologická data v reálném čase na server MQTT prostřednictvím bezdrátového připojení. Server pak dále poskytuje data pro aplikaci v počítači uživatele, kde program kreslí v reálném čase grafy na základě dat přijatých z MQTT serveru.

Device for automatic measurement of volt-ampere characteristics
Ondráček, Petr ; Vrba, Kamil (referee) ; Lattenberg, Ivo (advisor)
The Master's thesis discusses the design and realization of electronic meter of volt-ampere characteristics using Wifi module ESP32. The device is designed to be able to measure the characteristic in the voltage range of +/- 20 V and current range of +/- 200 mA. The device is controlled by web interface. The user is able to connect to it with for example his or her smartphone. This interface enables the user to configure various parameters, including the range of measurement and the power restriction. Furthermore, it is possible to graphically display the measured characteristic and export the data. To be independent on the outer network, the ESP32 is operated as an access point, which is creating a new simple network without the internet connection. In the Master's thesis, the principle of voltage and current measurement is explained theoretically, the circuit connection of device and the printed circuit board are designed and the cover of the device is modeled. Also the process of creating the device according to the design is described and the cover of the device is printed on 3D printer. After that, the control program is designed, described and uploaded into the resulting device. Finally, the functionality of the device is tested by measuring the volt-ampere characteristics of a few components.

Monitoring of production facilities
Borsuk, Adam ; Kiac, Martin (referee) ; Číka, Petr (advisor)
The aim of the diploma thesis is to study the possibilities of creating a monitoring system for older production facilities already in operation. Select the necessary components for the nature of the equipment to create a system that is able to capture and provide information about activities on the equipment. The second goal is to design a suitable communication model for clear information about the operation, sending and storing data. The third goal is to analyze the dual-core ESP32 microprocessor against its predecessors in the role of system control unit.
