About the calibration of BME680: Do you have a table where you have the sensitivity of the sensor (resistance) to every VOC? Or have you calibrated the sensor using a normalized/standardized mix of VOC? Trying to find out if this sensor is more reactive to some specific gases,(compared with other sensors).
Some other questions: Is the output static IAQ from BME680, also expressed in a scale from 1 – 500?
The IAQ accuracy reflects the current state of the background calibration process. Does this kind of calibration also apply to static IAQ?
