Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

In an NDIR sensor measuring CO˚, a Wavelength Filter placed just before the IR Detector only allows that wavelength of IR energy absorbed by CO˚ to pass through. The IR Detector measures the concentration of that wavelength of IR light after it has passed through the sample. Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using …

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration-it really is measuring the CO2 concentration!That means its a lot bigger and more expensive, but it is the real thing.

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift".

On-Chip Non-Dispersive Infrared CO2 Sensor Based On an ...

The existing CO2sensors can be categorized into 2 types: electrochemical sensors and non-dispersive infrared (NDIR) sensors. Electrochemical sensors measure the CO2concentration by measuring a change in the electrical properties of materials induced by the CO2adsorption. They have the advantage of being low cost and compact [11–14].

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 passes through the optical filter.
