Re: BMP085 - how to set altitude?

Code: Select all

 $ python Adafruit_BMP085_example.py
Temperature: 24.30 C
Pressure:    998.17 hPa
Altitude:    99.79
so if the altitude changed, how often do I need to set the MSL pressure in code?

Re: BMP085 - how to set altitude?

anyway, if I don't care about the altitude, is the pressure measured by BMP085 correct[b?[/b]
If you know an accurate MSL (aka QNH) pressure value, you can fine tune your altitude value.
I red that I can but I don't know how to do this...
