BME688 IAQ

[avfe]

Hello,

Page 17 of the datasheet (see attached) states that the raw gas sensor resistance values are transformed to an index for air quality (IAQ) by smart algorithms inside BSEC. Given that I am using the BME688 development kit, how can I access the IAQ values? The IAQ values are not included in the raw output files, and I cannot find a way to access the IAQ values using the AI studio. 

Thank you.

Hello avfe, You could refer the application note and web site. https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-bme688-an001.... https://www.bosch-sensortec.com/software-tools/software/bme688-software/

Thank you for your reply. The documentation does not describe how to use the AI studio to access IAQ data. It does seem to be possible to use the BSEC library to accomplish this, but not using the development kit. Is there any further documentation available?

Thanks

Hello avfe, 

Currently, we don't provide some value is included and some value isn't included for AI learning. 

What you can do is to gather gas in Lab or test environemtn and learn it. 

Thanks,
