Short-Term Forecast Based on Image of Sky
Volf, Martin ; Španěl, Michal (referee) ; Hradiš, Michal (advisor)
The bachelor's thesis submitted is dedicated to weather forecast based only on a video stream. At first, basic weather information which the sky can provide are presented. Cloud types including their properties and methods which the sky can most efficiently describe are dealt with. At second, basic circumstances between weather information are discussed. The objective of this work is to prove accuracy of the methods used for gaining data from the video stream and to find out whether it could be possible to use them for forecasting the rain, air humidity and sunshine for the period of time one hour later.

Automatic Weather Forecast Station
Kraicinger, Lukáš ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
Thesis is divided into theoretical and practical part. The theoretical part provides a brief overview of current sensors for professional weather stations and a list of affordable sensors and control units. The practical part describes the design and realization of a prototype station including processing and presentation of measured data. The thesis contains the source files and electronic wiring diagrams.

Electronic thermometer and humidity meter
Lapáček, Petr ; Chmelař, Milan (referee) ; Lattenberg, Ivo (advisor)
This master´s thesis deals with the design of measuring station used for the temperature and humidity measurement. There is a theoretical basical description of sensores for temperature and humidity measurement in the first part. Furthermore I deal with a theoretical design of measuring system, especially with types of materials and possibilities of communication between these parts. The main part of thesis is about communication on buses I2C,UART, SPI, RS485. There is a description of function procedure of particular integrated circuit, moduluses which are used in task in the next part of thesis.In the practical part I was engaged in a functional design of autonomous system for the temperature and ralative humidity measurement. Data could be presented by the computer after connection with the station. There is a description of testing the particular circuits and the full description of function particular blocks of system in the task. I have used the program called Eagle for schemes and printed wirings designing. The copy is placed on CD ready for next using. In the last part of thesis is a brief description of program algorithm "Meteostanice", which I have created for data presentation. There is an illustration of measuring results in these last part. The task is completely ready for the realization of autonomous system of weather station with its own memory.

Meteo weather station
Dvořák, Jiří ; Fajmon, Petr (referee) ; Fedra, Zbyněk (advisor)
The aim of this master‘s thesis is design and construction of home meteo weather station, the choice of applicable temperature, humidity and pressure sensors and characterization of workable device of station. The core of the station is microcontroller ATmega8 used for process data from sensors. Evaluative criteria for choice of sensors will be comunicate interface, accuracy, operating range, current drain and other aspects. Outer transmittin unit measure air temperature and relative humidity. These data are trasmitted by wireless radio module to interior receiving unit, that measure interior temperature and atmospherical pressure and represent measured data to LCD display including dew point. The data are transmitting to the internet and storing in the database. Measured values are available on the web page where you can display the graphs of last measured values.

Optimalization of solar park operation
Kašpařík, Petr ; Vaněk, Jiří (referee) ; Dolenský, Jan (advisor)
This work deals with the comparison of photovoltaic technologies and optimization of Photovoltaic power plants using empirical models. The primary purpose of this work is to analyse current status of selected photovoltaic power plants in the Czech republic and to suggest possible means to increase their productivity. This analysis uses data measured by systems for direct management of these parks, and these data are compared with theoretical data calculated from measurement system Czech weather stations and PVGIS.

Meteorological Station with Remote Access
Svoboda, Josef ; Číž, Radim (referee) ; Sysel, Petr (advisor)
This thesis discusses design and realization of air temperature, pressure and relative humidity measuring device, transmission of measured data over internet and their presentation on a web site. First chapter introduces reader into principles of measuring air temperature, pressure and relative humidity and various types of sensors used for measuring . Next, the conception of designed system is described. Designed system must accomplish tasks from reading raw data from the sensor up to thein graphical presentation to the internet user. Second and third chapter describes hardware and software design of air temperature, pressure and relative humidity measuring unit. In next part one can find description of software used to transmit measured data over internet and software for generating web pages which are shown to users. The work is revieved in the final part of this thesis.

The acquisition of energy data
VOJČ, Zdeněk
The bachelor thesis deals with the acquisition and processing of energy, specifically with the measured values of electricity production from the solar power plants. The work focuses on the entire process, from production, continual measurement of energy meters, meteorological data processing, and analysis of the measured data replacement values for the data processing needs of market operator. The result is a system design and software application that cover entire process with a focus on replacing the missing measure data through the analysis of meteorological data.

Modern methods of data acquisition
TŮMA, Pavel
This diploma thesis describes with simple bus 1-Wire technology, which is suitable for transfer of data measured by sensors. It describes the standard of bus and 1-Wire and iButton functional elements. This theoretical knowledge was applied during the construction of practical part. There has been a meteorological observatory constructed, which has been described in the next part of the diploma thesis. The last part of dissertation describes online distribution of measured values on internet.
