Question about the barometer.

[Deleted member 103366]

I think I have seen mention of the "opening to the barometer". If I am correct and if this opening is small what would happen if it becomes plugged air tight? I assume the barometer warms up as the innards of the drone warm up and I am wondering if the barometer could become pressuried ?
If so, if the drone was launched early in the warm up cycle could this force the drone into an uncommanded climb as the drone attempted to maintain pressure within the barometer?

This stems from there having been a number of threads about uncommanded climbs in cold weather (not related to a 'pressurisung barometer as the logs themselves showed an increase in height i.e. a pressure drop in the barometer) but it made me wonder what if?

The sensor itself is usually sealed with a small hole, so yes in theory that could get plugged, but in practice it's pretty much unimaginable that it would randomly get plugged, and even less so in a manner that's 100% airtight.

These modern Barometers are small, typically 3-5mm. The hole is very small, and I have never seen one get plugged up after using a few hundred of them.

Cheers!
