Im having the same issue. Im using the 2.5 APM in a Multirotor and the altitude is way off. what is the best way to cover the the barometer to make it more accurate?
Thank you for the reply. I have a new APM 2.5 with a case. Are you saying that with a case there should not be an issue? I don't need the cotton anymore with the case? The altitude seems to be off by about 20 meters most of the time. Luckily it is 20 meter high and not low.
Ill have to look inside. My case was already assembled with the board in it. Does anyone know if the barometer needs to be calibrated or if it can be?
Cool. Thank you.
Is the baro now reporting actual field elevation when coupled to the GPS? I show 5000 feet at start up and the baro does not reset to 0 when I arm. Yes I have foam covering the sensor with enough room for it to breath. I am at 5000 Field elevation that's why I find it coincidental.
Or is my sensor bad?
