Working Principle
PM sensor uses laser scattering principle: Light scattering can be induced when particles go through the detecting area. The scattered light is transformed into electrical signals and these signals will be amplified and processed. The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter.
CO2 sensor is NDIR based (Nondispersive infrared sensor).
