It seems that the you set too much delay inside the main process. BSEC can only support ~6.25% tolerance for the sample rate which means if the system delay is over 0.18 second under LP mode, the BSEC act this measurement as the first measurement again. Accuracy is 0 during first run-in time which is 5min under LP mode. In this case, sensors are always in run-in time. Please use standard example code and no extra delay for the main process. ...

Hi Sir:     If accuracy is not 3, the results is not used.  Long time is important for calibration, but environmental airflow also is necessary.     You should place sensor to a good ail environment or a bad air environment. Sensor know what is bad or what is good after change airflow around sensor. And its calibration will be finished.     ... View more

Hi, Have you already tried to change the address from primary to secondary? For example: iaqSensor.begin(BME680_I2C_ADDR_SECONDARY, Wire); Let me know   ... View more
