Access Control System Utilizing NFC and Arduino Microcontroller
Hájek, Jaroslav ; Štůsek, Martin (referee) ; Hošek, Jiří (advisor)
The Bachelor thesis focuses on acces systems including administration of locks, groups of users, users and their identities. For simple implementation of the system have been created four significant elements of the project: a web interface Locker, an application server Authentizer, MySQL database and an Android application. The web interface is used for system administration and included communication with the database. The server application is used for a communitation between the Locks and the MySQL database. The pivotal role of the server application is verification identities of users. The sever application and the database are used as publishing API. Android application is used as identity instead of identity card.

Compact System for Autonomous Meter Reading
Podeszwa, David ; Mrázek, Vojtěch (referee) ; Vašíček, Zdeněk (advisor)
This work solves the problem of the insufficient range of WMBUS meters, which makes their reading still difficult. The developed implementation solves this problem by using a battery-powered device that extends this range by using a LoRaWAN network, where the data received from the meters is sent over this network for further processing. The created device is capable of receiving WMBUS frames and sending them for a minimum period of 9 years. The main benefit of this work is the implementation of such a device on the new STM32WL platform, which is unique due to its integration of a microprocessor and a Sub-GHz receiver inside one chip.

Colorimeter for Medical Applications with NFC Connections
Šobich, Adam ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This Master’s thesis deals with assembling of a colorimeter using NFC technology. The theoretical part introduces the principles of colorimetric measurement, calibration curve, and important physical quantities. Further, the principle of NFC technology, its architecture, and division of NFC devices are described. The goal of the practical part is to propose a structural design and software solution of a colorimeter. Particular emphasis is placed on the selection of the RGB sensor that is being tested and its results are being analyzed. The construction of electrical circuit and microprocessor control are being solved. The manuscript deals with the implementation of an application for the Android operating system, which serves as the user interface of the colorimeter. Obtaining data from the sensor and storing it in a memory of the NFC tag is provided by the Arduino platform. Issues that were encountered during the work are analyzed in the discussion.

Wireless communication technology NFC
MÁROVÁ, Kateřina
Aim of this bachelor thesis is to handle the issue of new wireless communication technology NFC (Near Field Communication) including a comparison of advantages and disadvantages of NFC with other wireless technologies (Bluetooth, Wi-Fi, etc.). NFC is a technology for wireless communications between different electronic devices, one of which is typically a mobile phone. Near Field Communication allows wireless communication at very short distance by approaching or enclosing two devices and can be assumed that it will by used instead of credit cards, keys, IDs, etc. It will also support NFC technology researched by different mobile operating systems. Also creating a list of specific devices that support NFC technology. In this thesis a survey of the current expansion of this technology among professionals and laypeople in the Czech Republic will be carried out.
