indoor co2 sensor voltage

CO2 Sensor Measurement Range, Accuracy and Precision ...

As a rule, the narrower the range of CO2 measured, the higher the accuracy of the sensor. For example, if you were measuring 400ppm CO2 (fresh air) using a 100% CO2 sensor and the CO2 level increased to 500ppm, the change would be from % to %. This % (100ppm) change is outside the 100-300ppm range of accuracy of a typical 100% CO2 ...

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

Jul 11, 2017· Instead of calibrating at 0ppm CO2 (nitrogen), the sensor is calibrated at 400ppm CO 2 (outdoor air is actually very close to 400ppm), then 400 ppm is subtracted from the newly calculated offset value. Fresh air calibration is best for sensors in manufacturing settings or greenhouses where the sensor is constantly exposed to different CO 2 levels.
