Realization of narrowband powerline modems
Kubíček, Lukáš ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
This master's thesis deals with a narrowband power line communication technology (PLC) and focuses on the potential use in the sensor networks. This thesis addresses both the structure and basic properties of PLC standard and possible use of this application in practice. The main part of this work is implementation of the PLC networks with IC ST7570 of STMicroelectronics. As an example of practical use of PLC technology, this network is connected to the computer where the data from the sensor (meter) connected to a PLC modem, stored in a database using a PHP script as presented by the Internet. Problem solving in this thesis focuses primarily on the simplicity and universality of the resulting applications.

Web and mobile application for meteorological data collection and visualisation
Šturala, Martin ; Musil, Petr (referee) ; Caha, Tomáš (advisor)
The thesis deals with the development of a web application in .NET 5 and a mobile application for the Android operating system. The applications were created for the collection and visualization of data from the weather station, which was developed in previous years within the diploma thesis of Ing. Petr Mlčák. The web application provides a REST API for collecting data from the weather station and sending data for the mobile application, it also provides a user web interface for visualizing data from the weather station and managing it. The first part describes the quantities that the weather station measures and sends to the server. The second part describes the design of a database structure for data storage. The third part of the work is focused on the development of a web application in ASP.NET, its parts and structure. The functions and their meaning in the web interface are also described. The fourth part describes the design and development of a mobile application and the principles used for data acquisition and display. In the end, the results of the work and the method of testing applications are evaluated.

Acquisition of data on network communication from terminal devices
Obršlík, Lukáš ; Šedý, Jakub (referee) ; Krkoš, Radko (advisor)
The bachelor’s thesis deals with collecting statistical information about network communication in terminal equipment devices. Theoretical part of this project aims to gather methods and application tools on Windows and Unix platforms and support them by well chosen third party solution to gain more detailed informations. Tools were chosen based on ease of deployment and usage. Practical part of bachelor’s thesis directs to find suitable solution to gather detailed informations about network traffic. Important fact must be to not bother the end-users. Next part is to develop own application for collecting information about network usage and communication. Output format structure of the solution was designed with future data manipulation in mind.

Wireless sensors network for measurement of soil water potential
Rášo, Peter ; Klusáček, Stanislav (referee) ; Havránek, Zdeněk (advisor)
Cílem tohoto projektu je vytvoření bezdrátové senzorické sítě na měření sacího potenciálu půdy. Práce obsahuje výběr vhodné měřící metody obsahu vody v půdě, jejíž součástí je i tvorba kalibrač˘ní křivky. Dále se zabývá realizací hardwaru a firmwaru pro dva typy modulů. Stanice end station, obsahující snímač˘e, a základní stanice base station, která přijímá a přeposílá data. Celá aplikace je doplněna o uživatelský program, který umožňuje zálohování dat, zobrazování průběhů dat včetně dat předchozích, změnu nastavení systému spolu s možností žádosti o potřebné informace.
