Barometer pressure values are not unstable

When i run barometer example it shows very unstable reading. I converted pressure to altitude. Altitude is also not stable when board is fixed. But emlid site says navio has high resolution baro with 10cm accuracy.

I also have same problem. Barometer pressure is continuously dropped over a time.:worried:

Show me your log file, please.

It is impossible to tell anything from your question. What is your setup? What is actually wrong? Do you have logs, graphs?

Atmospheric pressure changes over time, pressure in your room can change when someone opens the window etc…

I used black sponge to cover barometer and problem solved. MS5611 is sensitive for UV rays. Thank you guys.
