    BME680 - unrealistic eCO2 Values

    Community Moderator

    Re: BME680 - unrealistic eCO2 Values

    Thanks for the update. Based on raw data signals, this time I believe the output looks as expected. If we look at the raw resistance signal from the sensor, we can see an actual step response from the sensor to some event. I cannot from the data only determine the origin or amplitude of this event, but something has been detected by the BME680, and this event is thus translated in BSEC outputs as well 🤔

    Ok, let's assume there was an event - even though I'm not sure what happened because the sensor is located in our office room and the air ventilation in the room works well.... and the peak is really high ...
    I will try to do some further tests.....
    Best regards!

    It could be as simple as someone coming back from a cigarette break getting close to the sensor, strong perfume smell, or simply farting.

    The source of air pollution might not have been CO2, but the sensor definitely detected something in the air.
