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.

IoT systems in diagnostics
Križanová, Bronislava ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master thesis deals with the topic of Internet of Things and its use in technical diagnostic. In theoretical part, there is a description of IoT systems and its parts, history of the IoT, communication modules and cloud systems. The second part of the thesis is focused on the description of technical diagnostic, diagnostic signal, and detailed description of two methods, most appropriate for use in IoT systems and that is vibrodiagnostic and thermodiagnostic. The practical part is focused on the application of the IoT system in technical diagnostics, including the measurement of vibrations and temperature, on the description of application in cloud system and analysis of measured results in cloud system. Prior to the end the more actions in this field of IoT systems has been recommended.

Smart weather forecast
Cigáň, Juraj ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This bachelor thesis focuses on the creation of an algorithm of automatically generated texts and their particular application in computer weather forecasts. It is aimed at gathering information from the fields mentioned above as well as about in the sphere of the software used to reach the set goals. The first part regards the history of development of digital generating and its present-day use. It specifies main rules and methods necessary to design such a programme. It also deals with the accumulation of required information for the designing of its own meteorological station and describes important features of the software, which can be used in such a process. Lastly, it also describes the creation of a programme which is able to gain and process information about weather forecasts and subsequently share them on social platform Twitter, all in consideration with the researches in previous chapters.

Measuring of Electricity Consumption Utilizing Current Transformer and Arduino Platform
Pokorný, Rostislav ; Pokorný, Jiří (referee) ; Štůsek, Martin (advisor)
The aim of this bachelor thesis is implementation of non-invasive platform for measuring the consumption and production of electrical power. Developed device enables visualization of measured data on display. Electric current is measured by non-invasive current sensor equipped with split core made of ferrite. Measured data are processed on single board microcomputer called Arduino. The device enables wireless communication with a server platform that allows visualization of measured data in a simple graphical user interface based on the ThingSpeak platform. Created device can measure consumption or production of electrical power on appliance with maximum current up to 30 A without need of any changes in electric circuit.

IoT House Plant Irrigation System
Jiroušek, Lukáš ; Kůdela, Jakub (referee) ; Šoustek, Petr (advisor)
The aim of this bachelor's thesis is to process a search of houseplant irrigation systems, to design and implement a houseplant irrigation system with sensing of additional parameters affecting cultivation using the Arduino platform. The scanned data can also be viewed using a graphical user interface. The ThingSpeak interface was chosen for this environment. To be notified of the necessary maintenance (lack of water, battery), an e-mail notification was selected, which is evaluated and processed by ThingSpeak itself. The system has been designed to be easily adapted to different pot sizes.

Temperature regulator with ESP8266
Vymazal, Tomáš ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
The bachelor thesis mainly focuses on a development of a smart socket thermostat able to communicate with a user and other applications via Wi-Fi interface in the 2.4 GHz band. Subsequent centers of attention are electrical temperature measurement and analysis of IoT clouds, currently used for logging and visualization of gauged data. Essential part of the work is the detailed depiction of PCBs development from their design to the particular stages of progress. The last but not least are the firmware measures and the regulation functionality verification.

Data concentrator
Dvorský, Petr ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
The topic of this thesis is the design and realization of a modular Data concentrator for various types of measurements in diverse conditions. The device conception, basic principles, design and functionality are described herein. Also, the lightweight protocol design for radio communication, standardized XML format for data storage and cloud usage are described. The electrical design of the device as well as the design of the printed circuit board was made using the Eagle Autodesk electronic design automation software (Eagle Autodesk EDA). The control software written in C/C++ for a target microcontroller (ESP32-WROOM-32) is based on a FreeRTOS platform and ESP-IDF framework. An IDE for managing this software is Visual Studio Code with PlatformIO extension. Selected and used Cloud Platform is ThingSpeak from Mathworks, which uses certain components from Matlab platform.

Návrh a realizace mobilní meteostanice
CHYTRA, Petr
This diploma thesis deals with the design and implementation of a portable weather station which allows you to measure air temperature, relative humidity, atmospheric pressure and especially the concentration of suspended particles in the air on which the work is focused. The portable weather station must be compact and have its own power supply. Part of the work is also the implementation of own measurements in selected localities.
