Barometer temperature

pixracer barometer in my custom quad can heat up to 44-45 degrees.
is it not critical?

Could you explain how get this graph… ?

Try reading the documentation on Analyzing Logs:

In State I can see press_temp 4431

Its 44,31 °C ?

If pixhawk can really measure temp, why my osd (minimosd with mavlink) displays 0°C ? (arducopter 3.5.5, works with another pixhawk with arduplane 3.7)
