Laboratory tool for teaching and demonstrating buses
Mutina, Petr ; Pristach, Marián (referee) ; Levek, Vladimír (advisor)
The goal of this bachelor thesis is laboratory tool design and realization, which is suitable for teaching and demonstrations simple buses (UART, RS-485, I2C, SPI, 1-Wire, CAN, current loop and IR transmission). Despite the fact there are many possibilities of signal transmission, this thesis deals with metallic buses only. The only exception is infrared light data transmission, that was added as an example of optical wireless communication. First, basic terms are defined and used technologies are described, then circuit design is made, finally, laboratory tool is made and tested.

Control unit for aeroponic growing system
Vrabec, Miroslav ; Dulík, Tomáš (referee) ; Klozar, Lukáš (advisor)
This thesis deals with the history of a method of plants cultivation without original substrate. The method is hydroponics and its subsequent development is called aeroponics. This work outlines the design of the whole aeroponic system including a control unit. The control unit has been designed to control the injection of nutrient solution, which is essential to the life of plants.Further, the control unit performs the control of lighting period, temperature, air flow and also regulation of nutrient solution pH. The control unit also keeps records of all data necessary for the monitoring process and for the evaluation of time differencies in the system.

System for Household Monitoring and Automation of Central Heating
Svoboda, Tomáš ; Nevoral, Jan (referee) ; Šimek, Václav (advisor)
In this work, which belongs to the field of embedded systems, several hardware modules and central control unit for home automation purposes were designed and subsequently implemented using 1-Wire bus and tiny computer Raspberry Pi. Furthermore, an extensive application for management of automation activities in a given system was created in C++ programming language. This piece of software is running continuously as a service from computer boot time until its shut down. There were implemented several functionalities that enable controlling the general purpose relay to switch home appliances and to operate central heating automation features, which include operating of electronic actuators on the radiator and boiler. In addition, web-based application allows direct monitoring of automation activities and provides necessary means to plan the desired actions of the available units within the automation system. Resulting system could be installed on a target site and monitor temperature, automate central heating and switch basic home appliances using relay. Main advantage of the created system can be recognized in scalability where new automation tasks or devices could be added.

System for temperature monitoring in server rooms
Papež, Milan ; Havránek, Zdeněk (referee) ; Macho, Tomáš (advisor)
The aim of this thesis is the design and implementation of a system for temperature monitoring in a server room that is able to send e-mail when exceeding the set temperature value. For this purpose was used PIC18F97J60 microcontroller that includes an Ethernet controller peripheral. Sending e-mail is realized via SMTP protocol, which is included in the TCP/IP stack provided by the manufacturer of the microcontroller. For temperature measurement is used DS18B20 temperature sensors that communicate via the 1-Wire interface. Device also allows the remote conguration. Temperature monitoring was tested using five sensors.

Wireles Flying Object Telemetry
Bednář, Martin ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This paper is engaged in specification, design and implementation of a telemetry module for flying object. Specifically, it focuses on the selection of the appropriate carrier frequency of the integrated circuit providing bidirectional communication to a sufficient distance and design of the protocol used in the transmission. Furthermore, the document focuses on the design of communication modules using these integrated circuits, altimeter sensor module, module to control the actuators and design of the application for mobile phones used to display the measured data. With regard to legislative and technical options, I chose a carrier frequency of 2.4 GHz. For this frequency is commercially available integrated circuit CC2511, which in cooperation with integrated circuit CC2591 should be able to provide telemetry range about 2 km. I chose BMP085 sensor for altitude measuring. It is communicating over I2C bus as well as a module for controlling the actuator, which uses a microcontroller ATMEGA48-20AU. The mobile phone communicates with the ground station via the USB bus.
