How interpretation works
1–1 of 1 guides
UV index: sunburn risk in a single number
The UV index condenses solar ultraviolet intensity into a 0–11+ scale. Above 6, take precautions. Above 8, every minute counts.
Circadian and ambient context
Time of day is a meaningful signal: many air-quality readings rise and fall with the sun and with the household's daily routine.
Lux and indoor-air context
Lux helps interpret placement, daylight, display behavior, and occupancy patterns. It is not proof of circadian lighting performance or WELL lighting compliance.
