Accelerometer output convention

A positive acceleration output will be produced when the sensor is accelerated at the same direction of the positive axes. When the sensor is at rest with Z axis pointing upwards, the calibrated output of the accelerometer is expected to be [0 0 +1g] indicating the acceleration due to the force of gravity.

Gyroscope output convention

Gyroscope output follows the right hand rule where rotation along an axis following the right hand convention will produce a positive angular velocity. The calibrated output of the gyroscope is expected to be close to zero when the sensor is at rest.

Euler output convention

Euler output is in degree. The rotation sequence follows global XYZ rotation. In other words, the current orientation of the sensor can be obtained by rotating at the euler values along global X → global Y → global Z axis.

Range of euler output is as follow:

• X Angle: -180° ~ +180°

• Y Angle: -90° ~ +90°

• Z Angle: -180° ~ +180°
