BME688 questions when detect VOCs

[Xin]

Hi, 

I am using this sensor to detect different VOCs. The reading is very stable when detecting. What's the minimum limitations when use it work for VOCs?

Under the same settings and hardware conditions, the data of one board is very stable, and the data of one board varies with the concentration. I just use different USB HUBs. What will influence its performance?

Hi Xin,

We haven't got the point "What's the minimum limitations when use it work for VOCs?", could you describe it again?
USB hub has no impact on sensor data.
