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.

Creation of a web application to select polymer materials based on mechanical properties for 3D printing
Kaziměrčíková, Lada ; Šafl, Pavel (referee) ; Binar, Tomáš (advisor)
This diploma thesis deals with 3D printing with a focus on the FDM method. Main objective of the thesis is to develop a web application which would assist in the selection of suitable polymer materials for FDM print, based on the required mechanical properties. The web application was created in Python with the usage of Flask framework and MySQL database. In order to develop this application, it was necessary to create an overview of material properties, mainly mechanical parameters and degradation mechanisms. Subsequently, testing in a climatic chamber was done, and also hardness and tensile tests for degraded samples. The collected data serves as the base of the understanding how given mechanical parameters may affect selection of the polymer material. The thesis then offers a practical instrument to help choose right material for FDM printing projects.
