How Do CO2 Sensors Work?

NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice. For CO2, the most commonly used wavelength is ...

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

Infrared light that makes it through the chamber and filter in the carbon dioxide absorption wavelength is then sensed by the detector. The difference between the light emitted by the source and the light sensed by the detector for the carbon dioxide infrared wavelength is used to calculate the gas concentration since the amount of light absorbed is directly proportional to the gas concentration.

How Is CO2 Monitored? Your Complete Carbon Dioxide Guide ...

CO2 monitors work by shining infrared light across the patient’s breathing tube. Carbon dioxide absorbs infrared light, so the more CO2 is present, the less light is picked up by the sensor. This allows the sensor to determine how much carbon dioxide a patient exhales. The sensor sends its data to a monitor, where it is displayed in two ways.

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.
