How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that ...
