Calibration it's OK if you have other CO2 sensors for reference, but for one sensor you have to go outdoors and set calibration base to 415 ppm (current CO2 in our planet).
This is still questionable - because your local air quality could be much different than the base earth #. We need a better calibration method than this.
Hi Larry, thanks for your request. If you’d like to learn more about the photoacoustic NDIR technology of our SCD4x compared to transmissive NDIR technology, please refer to our application note: sensirion.com/media/documents/9E7DA521/627C2C8D/CD_IN_SCDxx_Transmissive_and_photoacoustic_NDIR_sensing_D1.pdf Additionally: - Same as traditional NDIR sensors, the SCD4x sensor series offers highest sensor selectivity and accuracy - Sensor is available via all of our distribution partners, see for example here: www.digikey.ch/de/products/filter/gassensoren/530?s=N4IgTCBcDaIM4GMAmAWADCAugXyA Your Sensirion Team
Hi, the SCD4x has a digital interface and the maximum value is 40'000 ppm. You can find more information in the datasheet: sensirion.com/resource/datasheet/scd40/scd41

I am very much interested to know how accurate SCD41 can be comparing with other traditional NDIR CO2 sensor.

What is the maximum value of your SCD 4x CO2 sensor's analog output range

My Sensor didn't work, it doesn't get recognized from the control center, do u have any tipps ?
