Detailed Description

Measurement data produced by the SPS30 particulate matter sensor. Populated by sps30_Read(); check IsDataValid before using the values.

Mass concentrations (µg/m³) reflect the total mass of particles per unit volume, which is the metric used by government AQI indices. Number concentrations (n/cm³) count individual particles and are more sensitive for detecting early-stage smoke or combustion products.
