    Re: BME680 CO2 and bVOC always zeros

    Hi Sir:

         Please see my comments:

         1. IAQ    0 - 500  adaptive IAQ, esp. for mobile applications; scales sensitivity based on recent environment   (+-15) + (+-15%)

         2. SIAQ   0 - 10171  unscaled IAQ,  esp. for stationary / special applications; uses fixed sensitivity scaling.  no accuracy specified

         3. BVOC 0.5 - 1000ppm  estimates breath-VOC concertration to indicate current VOC level (derived form bVOC lab test)  no accuracy specified 

         4. CO2   400 - ... ppm     estimates CO2 concentration (derived from VOC measurement, uses average correlation in field studies)  no accuracy specified 

        More information you need contact bst local FAE to get under NDA.

       Hi Sir,

    Thank you for the information regarding my 1st question. I don't know why you missed my 2nd question. However, I make test on my side and observed that other accuracy status values are same as the AQI accuracy.

    Hi Sir:

        Correct, as you observed and thought, other accuracy status values are same as the IAQ accuracy.
