CO2 Sensor Calibration: What You Need to Know |

Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0 ppm CO2 (nitrogen), the sensor is calibrated at 400 ppm CO2 (outdoor air is actually between 350 ppm and 480 ppm in normal geographic locations), then 400 ppm is subtracted from the newly calculated offset value.
