Air quality sensors
Nitrogen compounds in air
According to https://www.rivm.nl/stikstof/monitoren-advies-onderzoek/overzicht-stikstofmetingen/metingen-stikstof-in-de-lucht average (typical?) values of
- Ammonia (NH3): 6.7 ug/m3 (9.6 ppb)
- NOx: 27.3 ug/m3
- NO2: 18.6 ug/m3 (9.9 ppb)
(ppb-conversion using https://www.breeze-technologies.de/blog/air-pollution-how-to-convert-between-mgm3-%C2%B5gm3-ppm-ppb/ )
