Metric guide
Quick ranges for the values shown on the dashboard. Treat them as operational guideposts, not medical or regulatory advice.
Temperature
Ambient air temperature around the sensor.
Comfortable
18 to 26 °C
Watch
12 to 17 °C or 27 to 32 °C
Poor
< 12 °C or > 32 °C
Comfort targets vary by season, but long stretches outside the middle band usually deserve a check.
Humidity
Relative humidity reported by the SHT21.
Healthy
30 to 60 %
Watch
20 to 29 % or 61 to 70 %
Poor
< 20 % or > 70 %
The middle band is usually the easiest range for people, materials, and electronics.
PM1
Very fine particles that can stay airborne the longest.
Low
0 to 10 µg/m³
Elevated
11 to 25 µg/m³
High
> 25 µg/m³
There is no single universal public threshold for PM1, so these cutoffs are practical operating bands.
PM2.5
Fine particles small enough to reach deep into the lungs.
Good
0 to 12 µg/m³
Watch
12.1 to 35 µg/m³
Poor
> 35 µg/m³
These guide bands are aligned with common indoor-air monitoring practice.
PM10
Coarser particles such as dust, smoke, and outdoor debris.
Good
0 to 20 µg/m³
Watch
21 to 50 µg/m³
Poor
> 50 µg/m³
Spikes here often point to dust, traffic, or nearby mechanical activity.
