Programmable timer configurable via USB
Dresler, Jan ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This thesis describes the design of printed circuit boards and programming AVR microcontroller, that communicates with the digital thermometer Dallas, also with photoresist circuit and RTC. Using sensors and relay allows switching of different devices. The switch allows direct configuration with computer via USB using the auxiliary circuit UART.

IR thermometer
Fridrichová, Jitka ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
These master‘s thesis deals with the issues of contactless temperature measurement, designe and construction of the infrared contactless thermometer. The thesis is concerned with the IR physical magnitudes and laws, methods of measurment and types of detectors, which are used for contactless temperature measurment. In the practical part of the thesis is created system design and block diagram of the IR termometer. In the next part of the thesis is presented system design, drawing of the printed circuit board and software processing of the IR thermometer. In conclusion are summerized our achieved resultes.

Temperature monitoring unit
Martínek, Jaroslav ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Content of the Bachelor Thesis covers design and realisation of an unit for multipoint temperature measuring in cooling and freezing equipments in food stores and shops. As a controlling microcomputer is used an Atmel ATMega128, temperature sensors are realised by DS18S20 digital thermometers, connected via 1-wire bus. Unit can read temperature from 32 temperature sensors, includes memory for measured data, real time clock, Ethernet interface and display with buttons for basic user control. Temperatures are measured periodically with user defined interval, values are stored into internal memory and showed on display. Measured data can also be transferred via Ethernet to clinent PC, where can be viewed in form of table and graphs.

Microcontroller controlled timer
Heralecký, Lukáš ; Macháň, Ladislav (referee) ; Pavlík, Michal (advisor)
Bachelor thesis entitled "Microcontroller-controlledtimer" is focused on design and practical application created a device that will be capaje of depending on external dating of simple tasks. This paperdescribes the features and capabilities of the microcontroller ATmega162, the Operations and program services. There is also described several other components used such as RTC, LCD display, matrix keyboard, temperature and othersensors. The first part is devoted to the oretical introduction to microcontroller and used parts. In another part ofthe PCB design - suitable layout of components, connectors, location, solving problems in PCB design. Fortesting functions designed and manufactured equipment is made simple test PCB. The practical part ended custom programming microcontroller programming language C.

Wireless modular system for device control and data acquisition
Pejchal, Luboš ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
The aim of this project is to design a cheap and simple modular wireless system. Its purpose is wireless control of remote devices and transmission of short information blocks (temperature data, status of controlled devices…). The whole system is controlled by a PC. It utilizes hybrid wireless modules for transmission of information and control of remote devices. The project shows practical usage of a digital thermometer communicating via a 1-Wire bus. A solar cell in conjunction with a DC/DC up converter is used to power low-power temperature sensor device.

IR thermometer
Kobza, David ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
This master's thesis deals with the issue of temperature measuring with the use of contactless thermometer. The thesis examines the physical findings, methods and detectors for contactless temperature measurement. Is then selected a suitable detector, measuring methods and assembled a block diagram of the IR thermometer. The main section is a specific system design. This includes circuit solution, including printed circuit board design and simulation of the functional parts.

Temperature Measurement in Technical Diagnostics
Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.

Temperature measurement
Brzobohatý, Lukáš ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
ABSTRACT Brzobohatý Lukáš: Temperature measurement The work presents a comprehensive overview of measurements of one of the basic state function determining the state of matter - the temperature. It deals with development of temperature scales, units and measuring devices. Temperature measurement is divided into two basic ways - contact and non-contact method. Contact measuring devices emphasis on thermocouples because of their indispensability in all industries. Non-contact temperature measurement is most developing method. This corresponds to the devices development, which is determined by the rapid computer technology development.
