TSI - BlueSky

General Description

The TSI BlueSky sensor provides real-time measurements of PM2.5 and PM10 mass concentrations, temperature and relative humidity. 

Principle of Operation

The TSI BlueSky sensor uses a Sensirion SPS30 light scattering single particle counter. The measurement principle is based on laser scattering using advanced particle size binning to covert particle number to mass concentrations through proprietary algorithms.
