Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

· The nondispersive 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, …
