How to Overcome the Disadvantages using Different CO2 sensors

2019-08-21· Chemical CO2 Sensor depends on the different gas sensitivity of the material, such as a classical chemical CO2 sensor MG-811. The chemical material itself has the highest sensitivity of CO2, but meanwhile, the chemical material is also sensitive to other gas like CO, Alcohol and other gas. If you want to get the real level of CO2 in the air, it needs to work with other gas sensors to calibrate ...

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, …
