Datalogger of environmental values
Raichl, Petr ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The thesis is aimed on construction of solar panel powered datalogger of environmental values. The thesis begins by research of commercial dataloggers. Then the concept of datalogger was created. Then the electronics of datalogger was designed. Datalogger is built as a system driven by microcontroller. The microcontroller reads data from sensors, writes data to memory card and sends data to Czech radiocommunications cloud by LoRa technology. Then the data are resend to MySQL database. Program for microcontroller was made in C language. Configuration of datalogger is done through USB interface by PC application which was created in C# language. For visualisation of measured data ASP.NET Core application was created.

Data logger
Dráb, Dominik ; Pazdera, Ivo (referee) ; Ctibor, Jiří (advisor)
This master's thesis deals with design of universal data logging device. The work proposes the design of device architecture and describes individual systems and components, that are necessary for data logging. Logger is designed as a mobile device, with ARM microcontroller at its core. Thesis specifies requirements for device in terms of performance and versatility. The device uses modular construction, as it comprises multiple PCBs. The thesis describes their design and also design of the mechanical construction of data logger. Designed device has been realized and assembled. Software design for microcontroller is also part of the thesis. In the last part, measurements to determine achieved parameters of the device are conducted.

ECG data recorder
Hruškovský, Antonín ; Krajsa, Ondřej (referee) ; Burda, Karel (advisor)
The master thesis deals with the issue of long-term ECG recording, used in medicine for monitoring of cardiac anomalies. Author focuses on explaning the general concepts in the first part. Author describes measuring methods and issues associated with measuring. Comparison of existing devices and design of solution with own features are in next chapter. Next is comparison and selecting of formats for recording measured data and description of device connectivity. In next chapter author focuses on hardware design and implementation of device. After that author describes software solution design for microcontroller, Bluetooth module and smartphone. Author introduces possible improvements for future generation of the device and then describes results of testing at the end of this work.

Data logger for serial communication lines
Jankech, Tomáš ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
The aim of bachelor’s thesis is the realization of data logger for serial communication lines. This paper describes basic concepts of serial communication and looks more deeply into RS232 and RS485 serial communications standards. It describes usual methods of data recording and their application in practice. Data logger’s block diagram is described in detail for each of its parts. Their descriptions contain an overview of circuits, which allows realization of individual blocks and circuit diagram of selected circuit. Following chapters describes design of printed circuit board, control application for PC and firmware for the microcontroller.
