BMP581 Calibration

[mgchoi]

Hi, BOSCH

There is no calibration in the data sheet of BMP581, so I checked and found that there is no need for calibration,
I found out that it was merged into Asic.

Then, I understand that there is no need to set with Driver like BMP390, but does it automatically correct?

What is the difference from the System of BMP390?

Hi mgchoi,

The comppensation formula of BMP390 was implemented in driver code. For BMP581, compensation formula part was integrated in sensor, user can get compensated data from BMP581.

Thank you for your answer.
So BMP581 doesn't need to be calibrated separately, right?

Hi mgchoi,

Calibration and compensation are two topics. BMP581 does not need to do compensation in driver code on host side. Whether the pressure sensor needs calibration depends on the application requirements.

I'm getting confused right now

Calibration is carried out during the product process, so there is no need to set it up separately,

Does Compensation need to revise it in S/W according to the app later?
