Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

2017-07-11· 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, …

2017-03-01· AC: The purpose of the sensors is to measure the amount of carbon dioxide and the location at street level at any given time. We then compare the data to simultaneous measurements collected from sensors located on a tower above the city, which allows us to calculate where emissions are coming from. For example, if the concentration of carbon dioxide is, on average, much higher at …
