Hi
How does the absolute vs relative accuracy relate for longer term barometric pressure measurements.
To be more specific :
If the sensor is placed in the same place for a longer period how would the accuracy evolve after a precise calibration (with 0.1 hPa accuracy) at that location. I was thinking 3 months to a year.
(10-30°C ambient temperature, coud be heated above 25°C in enclosure)
BMP390L :
absolute accuracy : 0.4 hPa (temperature 25..40 °C)
relative accuracy : 0.03hPa (temperature 25..40 °C)
long term stability : 0,16 hPa
BME680 :
absolute accuracy : 0.6 hPa (temperature 0..65 °C)
relative accuracy : 0.12hPa (temperature 25..40 °C, but constant humidity?)
long term stability : 1.0 hPa
