Transmitter and receiver for remote data transmission
Zimčík, Václav ; Toman, Marek (referee) ; Huták, Petr (advisor)
Bachelor thesis is focused on the construction of a multichannel thermometer with wireless data transmission. The device will be able to receive data from multiple transmitters, to which multiple temperature sensors will be connected, to one receiver by wireless transmission at a frequency of 433MHz, and then the device will display this data on a display using selected components and algorithm.

Wireless gathering of diagnostic data of cars supporting OBD-II
Fadrný, Jaroslav ; Kořínek, Tomáš (referee) ; Raida, Zbyněk (advisor)
Read up protocol OBD-II and familiarize yourself with the concept of existing devices, which use this protocol for wireless data transmission diagnostics car. Different conception mutually compare and suggest own concept device. The device should be consist from standard components without development own hardware. Implement the proposed device. Verify function of device and measure its range and data throughput. Discuss the connection to the database server and simple presentation of data.

Wireless controlled car model
Závodný, Vilém ; Škorpil, Vladislav (referee) ; Šteffan, Pavel (advisor)
The work deals with the analysis and practical implementation of advanced features in cars, which are responsible for greater passenger comfort and greater security for both passengers and other road users. All the work is solved on a remote-controlled model car, hence the need to deal not only with modern elements in cars, but also wireless data transmission, motor control, reliability of the system and a number of component problems. All these problems that occurred during work and their solutions are described in the following document. The work was based on the introduction of new items, modules and components that can be deployed as sensors, evaluation items, and other electrical and software components for the automotive industry in connection with electrical engineering and telecommuni- cations technology. Further work is focused on efficient wireless control of the vehicle, measuring environmental conditions and processing data so that they can be sent as soon as possible to the host PC or respond to them directly in the microcontroller in case of critical values.

Wireless sensor for indoor monitoring
Partika, Marek ; Jirgl, Miroslav (referee) ; Hynčica, Ondřej (advisor)
The work deal with programming interface for sensors and wireless transmission of the data. Communication with the sensor is solved by SPI and I2C protocol. For programming interface is used object-oriented programming techniques language C++. The wireless transmission of data is used XBee RF module. Here is proposed solution the correct format of data ready for send and method itself sending data. Data are received and displayed in the final application in the PC that is also able to send the selected data to the web, where data are displayed online.

Level indikator with wireless communication
Smatana, Tomáš ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
This thesis describes the design and realization of a device that is used for wireless measurement and control of liquid level. The first section explains the different options for level measurement, different implementation of wireless communication and describes the basic features of the Atmel AVR microcontrollers. Based on this analysis, appropriate solutions are selected sensors and wireless modules suitable for the design of the device. The second part is the design of a device which is subsequently implemented.

Wireless data transmission in ISM frequency band using Manchester encoding
Záděra, Zdeněk ; Němec, Karel (referee) ; Zeman, Václav (advisor)
This work is dedicated to the design and implementation of modules for the bidirectional transmission of data in the ISM band (Industrial, Scientific and Medical), used for private purposes, such as the transmission of telemetry data between mobile devices in the field. Delivery is solved by using RF modules RFM12BP the maximum power 500mW, these intelligent modules are controlled with microprocessor companies ATtiny2313 Atmel. Microprocessor is also used for the transfer of serial interface between computers and RF interface module. Utility for microcontrollers is written in C language development in middle CodevisionAVR. The project is designed in cooperation with the staff development center in Brno Honeywell.

Revision and further development of a cyber-physical measuring system for tool holders
Novák, Jiří ; Hänel, Thomas (referee) ; Holub, Michal (advisor)
Během obrábění se nástroj zahřívá a v důsledku toho se mění jeho geometrie. Za účelem měření teploty během frézování byl vyvinut sensorický upínač nástrojů. V rámci této bakalářské práce byl tento upínač nástrojů přepracován. Funkce byla rozšířena o měření zrychlení, aby bylo možné měřit vibrace během frézování. Kromě toho jsou použity nové komponenty a jiný standard pro bezdrátový přenos a byla navržena nová konstrukce. Dále byly provedeny pokusy, při nichž byla ověřena funkčnost nového měřícího systému. Odchylka naměřené frekvence vibrací přitom nepřesáhla 2 %. Konečná výroba upínače a integrace měřícího systému do nástrojového držáku nebyla součástí této bakalářské práce.
