    BME688 IAQ & co2 Equivalent

    BME688 IAQ & co2 Equivalent

    Using the BSEC2 library and the 'basic' example, I'm noticing that when reading values of

    BSEC_OUTPUT_STATIC_IAQ and BSEC_OUTPUT_CO2_EQUIVALENT 

    that the value of co2 equivalent seems to be 10 times time the value of static IAQ

    Is this an expected result?

    Hello, 

     

    Do you mean that CO2 value is 10 times larger than static IAQ? 

    No, CO2 and static IAQ are not directly correlated it. 

    Please let me know if you have further questions. 

    Thanks, 

    It must be a co-incidence.  Observation is that for higher values, there is the impression of a relationship.

    Hello MakerMan, 

     

    Of course, CO2 and IAQ are related. However, since we are IAQ tracking baseline, IAQ and CO2 values can vary. 

    It's certainly related, but you can't always measure like IAQ * 10 = CO2 value something like that. 

    Thanks,
