CO2 gas is composed of different types of atoms have absorption spectrum in infrared range. Absorption intensity abides by Lamber-Beer’s Law

CM1101 series adopts advanced non-dispersive infrared technology (NDIR) , which can be integrated in safety and alarming devices, able to be used for CO2 concentration detecting, air quality monitoring, HVAC, buildings, schools, medical, air conditioning, environmental monitoring, mushroom farming, fireplace ,CO2 controller etc .

Anyone has bought a similar one for indoor air quality monitor ?
