The AIR cartridge contains three sensors from the well-known manufacturer SENSIRION. The SGP41 is a MOx-based gas sensor that can measure volatile carbon compounds (VOC) and nitrogen oxides (NOx). The SCD40 is a photoacoustic sensor that can reliably measure CO2 levels in the range of 400-2000ppm.
The SHT40 is a calibrated temperature and humidity sensor. This cartridge outshines many room sensors in terms of quality, while also scoring points for programmability with added flexibility. (Requires an Oxocard CONNECT)
