PM2.5 refers to particles that are 2.5 microns or smaller in diameter. 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.
