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
