How to calibrate a CO2 sensor? - Yoctopuce

· Most serious CO2 sensors are based on the NDIR (non-dispersive 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 concentrations to ensure a correspondence between the detector measures and the actual levels of CO2. The advantage of the NDIR technology is that the sensor …

How does an NDIR CO2 Sensor Work? |

These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straight-path design.

Co2 sensor connexion and calibration | MySensors Forum

𝐸𝑀𝐹[𝑥]=𝐸𝑀F[350]− ln⁡(𝑃𝑐𝑜2[𝑥]/350) where EMF[350] is the voltage given in ambiant air (350 ppm of CO2). Now I am struggling to find the value of EMF at 350 ppm CO2. I connected my sensor module to Vcc=5V and to ground . Then i tried to measure Aout. Everytime I connect the sensor it gives a different value!

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0-400 ppm will be …
