It's not important,  sensor driver has remapping function to match sensor to desired position. ... View more

How about use the any motion interrupt as trigger. when any motion fired, then calcualte the movement directly from respect axis of gyro.  gyro give you the rotation speed according to this axis. Then use no motion interrupt to stop the calculation.  Then in this time window,  based on gyro sensor output, you can get out how much angle the door rotated.  Combined with the original position stored in your MCU, you are able to get the angle postion of door. You can also introduce a magnetic sensor to tell you the original postion like door closed.  ( magnetic field with highest value, sensor clsoe to magnitude).  ... View more

In this case,  you need de-solder the parts then send back to us for further analyze.  After deep analyze,  we can tell you if there is any damage in the sensor or not. Please contact your local FAE for the failure analyzing.  ... View more
