Drift in pressure sensor of MMC C

Hello there,
I am doing a vacuum monitoring over a long time (90 days for now) using the pressure sensor in the MetaMotion C. This sensor is the Bosch BMP 280 digital pressure sensor I assume.
It looks like some drift is occuring as we have a constant unexpected gain of pressure since few weeks now.
Does anyone alreday experienced that kind of drift, and how to detect it properly and correct it.

thanks in advance for your answer


  • No one has mentioned issues with the BMP280 on this forum. Maybe you can check the datasheet and bosch forum?
