BME 680 pressure

From my experience, the output of the 680 is very accurate. The BME680 can accept calibration values so the raw output is correct. But I think it would be easier just to try a local cal and input an offset in your code. We call that a “cal factor”. The pressure output of the 680 is linear so an offset may work.

And BTW, what are the units on your graph? :)
