What units are raw_temp and raw_press?

I’m looking at the status tab in Mission Planner in real-time and I’ve googled a lot and looked at the source and can’t find out what units raw_temp and raw_press are in. Temp doesn’t quite seem to be C or F and pressure doesn’t seem to be inches of mercury or hectopascals.

Thanks.

Temperature is in Celsius and pressure is in millibars. I noticed that the temperature runs a little hot and they think it’s because of the electronics that are near it.

Thanks. That explains temp, and I got millibars wrong because I was looking at pressure corrected for altitude on a weather website. We’re at 6000ft on the Palmer Divide just south of Denver, so the pressure is mid 800’s which is what IRIS+ is reporting.

Only the airspeed sensor gives correct air temperature. You can consider the other as PCB temperature.

Thanks, I don’t have an airspeed sensor, so another reason to get one.
