Design of complex sensor node for LoRa network
Obrtáč, Tomáš ; Sova, Václav (referee) ; Chalupa, Jan (advisor)
This thesis covers development of complex sensor for LoRa network. The thesis is extended by theoretical section, which explains basic properties of Lora network. Theoretical section also covers analysis of software and hardware products on market. The practical part of thesis is focused on creation of complex sensor and development of complete server for its operation. In the hardware part is described method of choosing the right sensors, designing the PCB and description of important parts. Software development is described from acquisition of network server, through creating the computer application, to programming the MCU.

Indoor flexible wireless CO2 measure system
Válek, Vít ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
Monitoring of the carbon dioxide concentration in the building is carried out for several reasons. One is to ensure hygiene conditions. With the advent of Bluetooth 5.0 came the support of mesh network technology, which is defined by the Bluetooth Mesh standard. By implementing this standard, we can create an extensive network of devices monitoring the concentration of carbon dioxide in the building. Based on the monitored concentration, we can control the air conditioning and ventilation of the spaces, ensuring that the hygiene conditions are met. Thanks to the compatibility of Bluetooth Mesh with Bluetooth Low Energy, it is possible to access individual nodes, e.g. from a mobile phone. The aim of this work is to design and implement a measuring system whose elements will communicate with each other using Bluetooth Mesh wireless technology.

Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

Modular Simulator of Microcontroller
Vosyka, Pavel ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis deals with design and implementation of new simulator with possibility of supporting multiple types of microcontrollers and has its own graphical user interface. The user interface was implemented using the QT graphical framework. Support for the ATmega328p microcontroller was added to the simulator using the simavr library. Three electrical circuits were modeled as microcontroller surroundings, these are switch, LED and RC circuit. The simulator was implemented in C++ and its functionality was verified. The result of this work is a functional simulator supporting simulation of microcontroller ATmega328p.

Smart lock device using CAN according to the AUTOSAR
Musil, Tomáš ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
The aim of this thesis is a creation of lock based on RTOS system according AUTOSAR standard. In the first part of thesis is the acquaintance itself with the standard. After that thesis is concerned with the choice of suitable RTOS and with this linked MCU. In the next point is described the method of creation of individual parts from which is an application created. The last points of the work concern the description of the application itself, functionality and methods of testing.

Electronic Chessboard on the FITKit Platform
Kubín, Jakub ; Zachariášová, Marcela (referee) ; Kaštil, Jan (advisor)
This thesis deals with the analysis, design and implementation of chess on FITkit platform. The platform is connected to the VGA monitor, on which is shown the chessboard with the figures. The game is controlled by using the keyboard on FITkit platform. The work describes the realisation of the unit for the display of the checkerboard that is implemented in the programmable gate field. Software of the microcontroller controls the depictive unit, generates possible moves and checks strokes of figures. There is a control whether the King does not have the check and if the game is not over because of checkmate or stalemate.

RF power meter
Hlaváč, Štěpán ; Jedlička,, Petr (referee) ; Drexler, Petr (advisor)
This master’s thesis describes various principles of measurement of electromagnetic waves in a free space and on a line. Used sensors and their real parameters are given for every method. The analysis of protections of high-frequency inputs of measuring instruments is done here and the most suitable method and protections of input for realization are chosen. The analysis of design of secondary protection of high-frequency input is done in this project. The protection of input is realized and measured. The suitable method of measurement is chosen as well as the sensor for measurement of power. The block diagram and circuit diagram of the meter of power are designed. According to designed conception the measuring instrument for measurement of power is realized and its single qualities are measured during the realization. In the final part its precision is measured and the evaluation of results is done.

Wireless sensor network
Beneš, Vladimír ; Pavlík, Michal (referee) ; Bohrn, Marek (advisor)
The bachelor thesis describes the design and implementation of wireless sensor network for temperature measurement. Network have to meet requirements for multi-hop network-type. That means, the sensor unit is out of the range, information about the measured temperature will be transfer between sensors. The sensor that is in range of the control unit will retransmit data from multiple sites to the main device. The sensors and the control unit are controlled by a microcontroller and a battery-powered for better mobility. The transfer of measurement data uses free zone for short-range devices - 433 MHz.
