    BME688 BSEC AQI Configuration - Gas Percentage Reading

    BME688 BSEC AQI Configuration - Gas Percentage Reading

    Hello,

    A few questions while using the BME688 sensor:

    • I'm using a BME688 sensor with BSEC in AQI config mode. The virtual sensor list gives a gas percentage value. What is this being measured against in the default config?
    • I'm looking to train a model for detecting environmental changes like smoke. Can this model be loaded without the device being in scan mode, given that my device is battery/solar-powered?
    • When using the BME68x API with BSEC, what are the pros/cons of choosing forced vs parallel measurement mode?

    Appreciate your help.

    Hi heyhaiden,

    About your questions, please refer the following reply:
    1. I'm not clear what gas percentage, do you mean you can output gas percentage in IAQ mode? Gas percentage value depends on the trained data which will be written in the config file.
    2. I'm afraid you can not do that, because estimation function can only run in SCAN mode.
    3. If you wants to test IAQ, you can only use Forced Mode, in contrast, you can only estimate what the kind of gas in Parallel Mode.
