Hello,
I am unable to reproduce CO2 and bVOC values different from zero for BME680. I am using the BSEC and even when have high values for IAQ (500) at output_ready() always get 0.0 for both CO2 and bVOC. Can you help me to reproduce some meaningful values?

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.
