The sensor also contains selfdiagnostics to assure proper operation during lifetime. · Use: Normal environments, such as offices, class rooms, hotel rooms, or other non-permanently occupied areas, typically reach at least once a week the CO2 concentration of fresh air of 400 ppm. However, exposure to a lowest CO2 concentration other than fresh air, or incorrect altitude parameter setting, might result in reduced accuracy and incorrect operation.
