BMP390 temperature compensation on the pressure values

[rena]

I used the BMP390. I have a problem with the pressure values in the shade and in the sun. It seems like the internal temperature compensation isn't working. What should I do?

Hi rena,

Thanks for your inquiry.
Because the material of the barometer is semiconductor, there will be a radio effect when light shines on the semiconductor, which will affect the measurement results of the sensor.

Thank you for your reply. I haven't noticed the affect of sunlight yet, but I definitely see that the barometer's pressure changes with temperature. According to the datasheet, the pressure should be compensated by the temperature and pressure coefficients from the barometer's NV memory. Please check the graphs below.Thanks.
