How does an NDIR CO2 Sensor Work? |

Modern NDIR CO2 sensors. Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· The non-dispersive infrared (NDIR) carbon dioxide sensors rely on an infrared light source and detector to measure the number of CO 2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO 2 molecule counts. To combat sensor drift, during calibration a sensor is exposed to a known gas source, multiple ...

Quantitative measurement of combustion gases in harsh ...

So far, CO2 detection in IC engines using NDIR has been limited to empirical approaches, which proves to be valid only under a certain condition, , concen-trations <4% and pressures >4bar (Vanhaelst et al.,2013). Here, we apply a physically reasonable procedure based on spectroscopic data from the HITRAN database to quantify CO2 as well as H2O. For each sensor, we describe the field of ...

Cubic Dual IR Source 5,000ppm NDIR CO2 Sensor -

Using patented two-engine technology, this sensor uses 2 IR light sources - one for measuring the CO2 level and one as a reference. By comparing the two light sources, the effects of temperature and humidity are minimized, and light source aging can be automatically compensated for, resulting in longer life, greater stability and reliability.
