CO2 Sensor Calibration: What You Need to Know |

+

Most of our CO2 products use nondispersive 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".

LMP91051 NDIR CO2 Gas Detection System ... below shows the basic NDIR gas sensor working principle. Figure 1. NDIR Gas Sensor Principle Gas molecules will absorb radiation energy from the lamp emission. Absorption follows the LambertBeer law: I = I0 * ekcl Where I is the transmitted IR intensity at the thermopile detector side, I0 is the initial intensity at the IR source, k is the gas ...

Basic Principle of NDIR Gas Detection Heimann Sensor

+

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

NonDispersive Infrared, NDIR, Carbon Dioxide Sensors ...

+

A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes ...

Nondispersive infrared sensor Wikipedia

+

NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs.
