Workplace environment monitoring platform
Lipták, Ivan ; Dvořák, Jan (referee) ; Musil, Petr (advisor)
This work focuses on the design and construction of a platform for measuring air quality in the workplace. The platform will collect data on air conditions and subsequently evaluate this data for further processing into a database or possibly alerting the user. The platform will utilize an ESP32 microcontroller, to which various sensors and a display for real-time data visualization will be connected. The design will emphasize on the highest accuracy, flexibility of the device, and its diverse applications in manufacturing halls, offices, or even homes.

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.

System for measuring of thermal efficiency of solar absorbers
Řiháček, Jan ; Podaný, Kamil (referee) ; Mrňa, Libor (advisor)
The thesis deals with the measurement system for determining the thermal efficiency of the newly developed types of solar absorbers. Measuring equipment allows simultaneous indoor or outdoor thermal efficiency detection of up to four samples absorbers. Emphasis is placed on the flow and heat transfer medium temperature changes. For this purpose is used Biotech FCH-m-POM-LC and LM35DZ sensors. Sensor signal is transferred to a PC using the measuring module NI USB-6221. Here it is further processed by proposed evaluation program. The software is implemented in LabVIEW integrated development environment. In a final part are performed a verification measurements to assess system performance and evaluate the thermal efficiency of various types of solar absorbers. This path is also demonstrated high efficiency applications absorbent layer coating color RABSORB 5.

Measurement of selected physical quantities
Zajíček, Matouš ; Štěpánek, Vojtěch (referee) ; Pruša, Radomír (advisor)
In the introduction of this thesis a brief literary research of existing types and principles of function of selected sensors of temperature, atmospheric pressure, relative humidity, weight and island electric energy sources is performed. The next part is focused on realization of measuring system, meant for usage on beehive, using Arduino development platform. In the final parts of thesis, a control measurement, verifying function of the system, is performed and energy consumption is evaluated, along with designing a suitable power supply.

Temperature control and monitoring system
Mitter, Martin ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This work is dealing with the design for maintaining and monitoring optimal temperature for home-based data center. The purpose of this work is to prolong the life of hard drives in data center for as long as possible. First of all, the attention is given to establishing what the optimal temperature for maintaining long-live of hard drives is and how to correctly measure it. Based on the knowledge obtained from theory and from the prototype testing the final design of embedded system for maintaining this function is created.

Network datalogger
Maštálka, Daniel ; Žák, Jaromír (referee) ; Šteffan, Pavel (advisor)
Work is about theoretical proposal of network datalogger, which logs indoor and outdoor temperature and humidity. As microcontroler is used development kit STM32 Value Line Discovery and for comunication with server is used Ethernet protocol. As primary display is used remote access to server, as secondary alphanumeric liquid crystal display.
