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 ...

So CO2 will build up in a room with poor ventilation, just as COVID-containing aerosols will. With schools, and other places of business, returning to in-person activities, it is challenging to know the air quality in a room. CO2 sensors are a pretty good way to indicate how dense the amount of previously-respired air in a space is, and therefore how much potential COVID could be in the air. There are …
