How to calibrate a CO2 sensor? Yoctopuce

20150501· So, do we need to calibrate a CO2 sensor and, if we do, how should we do it? Most serious CO2 sensors are based on the NDIR (nondispersive infrared) technology, consisting in measuring the number of CO2 molecules between a particular infrared light source and a detector. At the factory, the sensor manufacturer must perform a full sensor calibration with different CO2 …
