IR vs TC: Settling the CO2 sensor debate once and for all ...

26/07/2016· 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 …

User Manual - ETCO2 Sensor - Cables and Sensors

The ETCO2 sensor uses an infrared absorption (IR) technique for monitoring CO2. The principle is based on the fact that CO2 molecules absorb infrared light energy at specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When the IR light beam is passed through a gas sample containing CO2, an electronic signal from the photodetector can be ...

How do the sensor and CO2 sensor work? | AirVisual ...

How does the IR CO2 sensor work? The CO2 censor is composed of an infrared (IR) lamp, a reflective gas cell, and IR filtered detectors. The IR lamp sends waves of light towards the IR filtered detectors, which can measure how much IR light reach them. While the IR light goes through the cell, CO2 modules absorb lights of certain wavelength (shown in the graph). Thus, the number of CO2 modules ...

NDIR simply means that the sensor uses a narrow-band IR light not generated with a spectroscopic dispersive element (such as a diffraction grating), but with more recent technology, such as an IR LED. The wavelength of the IR light overlaps the mid-IR spectrum band, where CO² absorbs IR from 4186 nm to 4211 nm. When CO² penetrates into the sensor's sample diffusion area, it absorbs the IR ...
