    BME680 tVOC as ppb

    BME680 tVOC as ppb

    Can the BME680 provide an absolute VOC level as ppb or ug/m3 rather than the IAQ Index?

    We are attempting to comply with an indoor air quality standard where we must be able to sense TVOC in the range of at least 65-870 ppb.

    Hi ,

    BSEC has an estimate output of VOC level, named BSEC_OUTPUT_BREATH_VOC_EQUIVALENT in ppm. You can find details in the BSEC release folder.

    Hi, would you please tell me where I could find this document? Thank you!

    Datasheet of the BME680 can be found on its product page. The most recent BSEC package can be downloaded from its dedicated page on our website, which includes a short integration guide, some example code, and the library's header files that also include useful information.
