PMSA003I Air Quality Breakout - STEMMA QT/Qwiic

Witness real-time, reliable measurement of PM2.5 dust concentrations with PMSA003I from Plantower. This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time. The microprocessor calculates equivalent particle diameter and the number of particles with different diameter per unit volume.

• PM1.0, PM2.5 and PM10.0 concentration in both standard & enviromental units
• Particulate matter per 0.1L air, categorized into 0.3um, 0.5um, 1.0um, 2.5um, 5.0um and 10um size bins
