How to monitor indoor CO2

CO2 is a gas and cannot be effectively monitored using the standard light-scattering laser sensors commonly used for measuring PM. Instead, the most accurate method for measuring CO2 involves sensors that utilize infrared (IR) light to estimate the concentration of CO2 molecules in the surrounding air.

  1. How to monitor indoor CO2 Presented by Hibouair.com

  2. CO2 is a gas and cannot be monitored with typical light-scattering laser sensors used to measure PM.

  3. Instead, CO2 is best measured with sensors that use infrared (IR) light to estimate the number of CO2 molecules in ambient air

  4. Here’s how this works

  5. Ambient air passes through a CO2 sensor assembly made up of an IR light source, reflective gas cell, and IR light detectors.

  6. IR light shines onto CO2 molecules that pass through the assembly. The CO2 molecules absorb much of this light.

  7. The remaining light that isn’t absorbed by CO2 molecules passes through to detectors.

  8. IR light detectors calculate the change in IR wavelengths from what was produced by the IR light source to what remains after CO2 absorbs the IR light.

  9. The change in wavelength indicates the concentration of CO2, which is converted to a ppm reading

  10. A standalone CO2 sensor may indicate the presence of elevated indoor CO2 and meet basic CO2 monitoring requirements for workplaces and schools.

  11. A study published by the ACS suggests that indoor CO2 levels may be one tool to help
