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, …

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. The band of IR ...

Pyroelectric detectors for gas analysis from InfraTec

A pyroelectric sensor generates a signal as soon as it is illuminated with an electrically or mechanically modulated infrared source. By integrating a gas-specific narrow band pass filter, which is tuned to a specific gas, the pass band is spectrally limited. The installation of a CO2 standard filter with a CWL of µm and a HPBW of 170 nm means that only radiation in this wavelength range will impact with …
