Measuring and Data Logging of Air Parameters
Kaziměrčíková, Lada ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
The goal of the Bachelor thesis is to design a device for measuring humidity, temperature and CO2 concentration with implemented data logging. The Raspberry Pi computer was chosen as the control unit for the design of the device with three sensors, DHT11 for measuring temperature and humidity, NDIR MH-Z16 for measuring the CO2 concentration and NOVA PM SDS011 for detection PM10 and PM2,5 particles. The measured data from the sensors are stored in the MySQL database and are displayed on the web using PHP scripts and active Javascript elements. The Bachelor thesis also focuses on the analysis of air quality and the substances contained in the air with presented research for sensors used for measuring the concentration of these substances.

Application of activated carbon in flue gas treatment process
Navrátil, Petr ; Niesner, Jakub (referee) ; Jedlička, Filip (advisor)
The objective of this bachelor thesis is to explain the problematic of flue gas treatment from the air pollutants mainly by methods using adsorption on activated carbon. There is an introduction to environmental protection, description of selected chemicals, charcoal and description of technologies to remove pollutants in municipal waste incinerators, and finally mention the possibilities of disposal or reuse of a saturated carbon. And finally selection of appropriate methods and design for a specific application.

Tracking Air Pollutants by Using Wireless Sensor Network
Válek, Tomáš ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
This thesis discusses design and production of a prototype of a device and implementation of a firmware for this device. Its function is to wirelessly monitor a concentration of pollutants like carbon monoxide and propane-butane in an atmosphere. Motivation is to allow parking of vehicles with engine gaseous fuels in underground collective garages for public use according to ČSN 73 6058 standard. The prototype of the device has been designed so that it could be used not only in collective garages but also in garages of family houses. The device was successfully designed, produced and programmed so that it can be deployed in real-world conditions.

Vertical gradient of ambient air pollutant levels
Binda, Denis ; Hůnová, Iva (advisor) ; Zíková, Naděžda (referee)
Ambient air pollution, caused by harmful pollutants, is considered a severe problem for the natural environment and its components. Effective pollution regulation is possible with reliable data from monitoring stations covering the whole country. Those stations are mainly located at the altitude of 2 m above the surface, possessing their well-known horizontal representativeness. However, the knowledge of the vertical representativeness of these monitoring stations is not sufficient, causing problems while determining the relevance of these measurements for studying the effects of pollutants in various altitudes. The gradient of ozone concentration (determining the change of ozone concentration for each 10 m) was computed to determine the vertical profile of tropospheric ozone (the gradient in this work is using the unit [μg.m-3 /10 m]). Data, containing the ozone concentrations, were measured in altitudes of 2, 8, 50 and 230 m and sourced from the National atmospheric observatory Košetice in the time interval from 6.9.2013 to 31.12.2020. The ozone concentrations show a yearly periodicity, with higher values during the summer period (from 1.4. to 30.9.) and lower values during the winter period (from 1.10. to 31.3.). The gradient for layer 230-50 m outlines considerable stability throughout the year...
