RFID acces system realization
Buchal, Adam ; Matyáš, Pavel (referee) ; Marada, Tomáš (advisor)
This bachelor thesis deals with the use of RFID technology in access control systems in intelligent buildings. The study also describes the principle functions of RFID readers and the list of frequencies at which the technology works. The next section is dedicated to the design of the access system with iClass R10 operating at a frequency of 13.56 MHz, the whole system is controlled by a microprocessor ATmega8. The board design is described program for creating electronic schematics EAGLE. The try-out functionality and basic programming functions used kit EVB 4.3 The last section describes the procedure for the production of printed circuit boards photo path including drawings and schemes and also describes the program controlling the entire device using the block diagram.

Image processing algorithms in eight-bit microcontroller
Rébl, Miroslav ; Fajmon, Petr (referee) ; Fedra, Zbyněk (advisor)
The aim of master thesis was to investigate a simple camera and processor Atmel AVR unit implementation. Thesis describes how to get image from C3088 module and management over the bank of camera registers. Work includes limitation draft for this way of processing the information. Thesis also solves an exemplary model for object recognition using this implementation.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

Weight sensing of beehives with long-term stability
Vozdecký, Martin ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
The aim of the thesis is to describe the design of stable measurement of weight in beehives. Work evaluates suitable types of weight sensors and their effect on stability. The main part of the thesis is a custom design of electronic sensing the weight of the beehive and telemetry data to the user. The concept of engagement enables stable measurement of mass loading of independence on the ambient temperature.

PH controller for aquarium
Dvořák, Jan ; Fedra, Zbyněk (referee) ; Šebesta, Jiří (advisor)
This bachelor’s thesis deals with the system which is designed as a pH regulator for aquarium water. The first and second chapter are aims to the basic requirements and possibilities on controlling of the potential of hydrogen in water. Main methods of the pH measuring, its controlling and regulation are included. The third chapter presents a design of the pH regulator system. The practical and software solution of this project is presented in the fourth and fifth chapter. There are described in detail the main blocks of the pH regulator - amplifier, galvanic isolator and output power stage. The results of the testing and measuring of the designed subsystems are introduced in the last part of the work.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.
