`SCALED_PRESSURE` is used for the pressure sensor onboard the autopilot, so is a pressure reading from inside your enclosure. That’s generally more useful for aerial vehicles (e.g. for determining altitude of a drone), but can also help determine if there’s an excessive pressure in an enclosure.

The Bar30 measurements get reported via `SCALED_PRESSURE2`.
