TVOC and eCO2 Sensors • Wolles Elektronikkiste

2021-07-02· So forget the absolute values! The TVOC and eCO2 sensors give trends, nothing more. If you really want to monitor the CO2 content of the room air, you’d better use the slightly more expensive NDIR CO2 sensors. SGP40 . Meanwhile, there is a successor model of the SGP30, namely the SGP40. Instead of TVOC and eCO2 values, this device provides a ...

MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

2021-06-12· NDIR measuring principle of the CO2 sensors. Non-dispersive infrared sensors (NDIR) measure the CO2 content of the air via the absorption of infrared light. The fact that CO2 absorbs infrared light is something you know from the greenhouse effect. Sunlight passes relatively unhindered through the atmosphere and the CO2 it contains. The heated surface of the earth radiates the energy partly in ...
