Pressure sensor problem

Posted by Jordi Salvador on October 28, 2014 at 9:34am

Hi,

I was doing some tests today with an APM 2.5 and discovered that the pressure sensor was reading continously decreasing values (see attached image). This may be because of a sensor failure or because of some parameter that is not correctly set in the firmware/software?

Thanks!

    Did you wait for the sensor to get up to temperature? it will change as it normalizes, and the scale only show 2.106 for high and low, so the change looks very small, it's only cm

      Thanks for your help.

      I waited something around 5 minutes without changes, you can see in the attached image how the altitude decreases around this time something around 1000 meters...
