I want to find out how accurate and how relyable the APM 2.5 sensors are. The sensors that I'm interested in are: baro, airspeed, compass and acceleration. Do you know whether the sensors are calibrated at 3DR or maybe at their original factory?
To get the accuracy I also need the resolution of the sensors. I already had a look into the datasheets but not everthing is clear for me.
Thanks for your help!
