What are the measure’s unit for NOx and VOC and why they are not accessible on the airgradient map (like also Temperature and Umidity) ?
If we’re talking about the SGP sensor, it is an arbitrary index. How to interpret it is described in this document: Sensirion Info Note: VOC Index. There’s a similar document out there about NOx index too.
and why are not those data published ?
and why T and HR are nt on the map ?
