Jul 11, 2017· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.
Indoor Carbon Dioxide. Indoor carbon dioxide concentrations are strongly correlated to human metabolic activity. People are the main source of carbon dioxide emissions in indoor environments due to CO2 being the main gas emitted during respiration. The higher the number of occupants in a building, the higher the concentration of carbon dioxide.
