the operating temperature of the BMP388 is given from -40°C - +85°C. But the absolute accuracy for 300.. 1100 hPa is given only from -20 ... 65°C with 0.5hPa and also the temperature sensor accuracy is given only from 0.. +65°C. In our planned application we will see temperatures up to 80°C.
1.) What is the absolute accuracy between +65° .. +85°C and -40° ... -20°C?
Unfortunately if a specification is not published in the datasheet, it is usually not publicly available.
Is there any possibility for me to get in contact to a engineer, who can supply me informations how the BMP388 will behave up to 85°C?
