CO2 Levels Relate With Airborne COVID-19 Spread | HVAC News

Using low-cost and compact CO2 sensor devices can help to warn against high concentrations of CO2 in the air, and by extension, the likely higher levels of aerosols and greater virus spread. Seeking to provide a warning of high CO2 levels (and thus a likely higher concentration of aerosols) points to a need to increase deployment of inexpensive CO2 sensors in a variety of applications.
