Sep 28, 2018· CO2 sensors can be broadly broken into 2 camps: nondispersive infrared (NDIR) and electrochemical (EC). If you breath on them, both will measure a change in CO2, but there are differences. NDIR sensors include SenseAir, GSS, Teleaire by Amphenol, Winsen, Figaro (new), and others. They tend to be faster, last longer, and are more accurate.
