built-in air quality sensor module / VOC / CO2

Air quality sensor module AM4100 integrate PM2.5 CO2 VOC RH&T sensor, can detect particle quantity of size from 0.3um , CO2 concentration, VOC concentration, related humidity and temperature. It adopts laser scattering technology for particle measurement, NDIR technology for CO2 measurement, electrichemical technology for VOC measurement, and resistance material for indoor related humidity and temperature measurement.
