How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount ...

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

This CO2 sensor module is designed to monitor 05,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dualinfrared source principle, the CU1107 sensor compensates for longterm drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent ...

Why does my CO2 sensor read zero after calibration?

The answer / solution to the problem / question documented in this article. The Carbon Dioxide IR sensor is calibration sensitive it needs to have a twopoint calibration performed in the proper order. Zero calibration with 100% Nitrogen gas, zero air or any gas matrix that does not have CO2 to calibrate your baseline. Span calibration with 5000ppm (5%) CO2 gas. The 5000ppm Span value is the ...
