This thesis compares the methods for the determination of air and moisture condensation in the construction. There are descriptions of the various methods and formulas for measuring humidity and methods for the calculation of condensation in building structures. The practical part describes the development of a method for verifying the condensation of moisture in construction. Parts of this work are the materials and methods for the development of the humidity sensor. There were used two methods – capacitive and resistive for measuring moisture condensation. In the conclusion is the evaluation of the humidity sensor and compares the results of individual measurements.

This thesis deals with the design of overall concept of distributed system which is used for temperature, pressure and humidity measurement. The system is adapted to be used in instrument transformers and sensors production hall of ABB s.r.o. Brno. Firstly, the requirements for the measuring system are defined. After that market research focused on sensors and measurement modules is performed. The selected sensor is afterwards built into own measurement module for which hardware and software part is designed. The work continues with design of local and remote database of measured values. Besides, the PC software used for local and remote data storage is designed afterwards. The components of the measurement system are tested in the final part of the thesis.

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.

This thesis treats concept of autonomous temperature, relative humidity and pressure USB datalogger. Also there is explained datalogger function, hardware design with respect on device consumption and design of chassis. Furthermore, there is described communication protocol for control and reading out data by the PC. Furthermore, there are described firmware drivers for some used components and modules for USB communication, RTC and data compression. Lastly there is described software which is used for datalogger configuration and data read out.

Diploma thesis deals with design of measurement and control system of an air-ground heat exchanger, which is placed in area of FME BUT in Brno. System is built in development environment LabVIEW and it is using modules CompactDAQ from National Instrument. Developed system managed trial operation, during which was designed additional changes of measurement equipment for determine another magnitudes, which help us with future evaluation of benefit of air-ground heating exchanger. It was designed some operational modes, which solve different ways of control air-ground heat exchanger.

Agrivoltaic systems work on the principle of combining farmland with Photovoltaic energy conversion giving the land it sits on dual purpose. Moreover, by combining solar electricity conversion and crop production additional benefits such as water saving and, in some cases even higher crop yields compared to open field conditions. For this technology to be wildly implemented a deeper understanding on the effects the agrivoltaic system has on the underlying farmland is required. In this work, an IoT sensor station used for monitoring albedo, temperature, and humidity inside an agrivoltaic system is developed. The work is carried out through researching and testing electrical components that is to be used inside of the monitoring station as well as development of the code used by the microcontroller to communicate between the different sensors. The prototype station was then tested a total of three times at Kärrbo Prästgård and the gathered data compared with pre-installed sensors located at the testing site. After each test run the IoT stations performance was analyzed for potential improvements to be implemented before subsequent tests. The final design of monitoring station showed a high accuracy in the albedo data during daytime with some deviations during early mornings and late afternoon due to the inherit limitations in the sensitivities of the electrical components used to measure solar radiation.

The thesis deals with the environmental assessment of buildings, concrete objects Letní lázně at Karlova Studánka. The first part describes the issue and legislation. There is also described a method of experimental measurement and methods of moisture measurement. The second part deals with the analysis of the specified object, description of selected renewable sources and description of possible modifications of the object. The third part is devoted to modeling and simulation of the specified object in DesignBuilder. Using the model were created various simulations with various modifications in order to reduce energy intensity of the object. Results were then evaluated and compared.
