Why does the output value of MH-Z16 fluctuate?
Environmental concentrations vary greatly.
The concentration of CO2 exhaled by the human body is in the range of 1%~5%VOL (10000~50000PPM)
When people are in a normal environment (a clean air environment with a CO2 concentration of about 400PPM), such as offices and conference rooms, the CO2 concentration range will range from 600 to 2000PPM, or even higher.
