Carbon Dioxide Absorbs and Re-emits Infrared Radiation ...

CO 2 molecules can vibrate in ways that simpler nitrogen and oxygen molecules cannot, which allows CO 2 molecules to capture the IR photons. Greenhouse gases and the greenhouse effect play an important role in Earth's climate. Without greenhouse gases, our planet would be a frozen ball of ice. In recent years, however, excess emissions of carbon dioxide and other greenhouse gases from human ...

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.

Infrared Sensor Technology and its Impact on Measurement ...

After installation, HVAC CO 2 sensors can typically operate with little or no maintenance for years, even for their entire lifetime. Selecting a sensor capable of reliable and accurate measurements in the long-term is therefore important. Although all infrared CO 2 sensors share a common measurement principle, the technical solutions and measurement performance differ greatly. A well-trained ...

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

· IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter. Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 levels would cause more IR …

How does an NDIR CO2 Sensor Work? |

Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or "fingerprint" to identify the CO2 molecule. As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength absorbed by CO2 …
