Detekce a vizualizace koncentrace plynu pomocí minipočítače

Abstract

This work describes gas detectors in industry and gas sensors, which are supported by minicomputers. When working with gas, their safety in use is described here. In the practical part, a station for measuring and evaluating gas concentration is designed and connected, which consists of Raspberry Pi 3B +, gas sensors, touch screen for Raspberry Pi, PCB for communication between sensors and the measuring station. The work examines and evaluates the gas concentration in the measuring station and regulates the ventilation of the gas by fans. The software, including the graphical environment, was created in the QtCreator programming environment.
