2.3 Axis of rotation

Axial diagram of rotation detection-mems gyro

Fig.3 Axial diagram of rotation detection

The MEMS gyro is a single-axis high performance gyroscope that detects the rotary axis perpendicular to the chip surface.

Counterclockwise rotation along the axis of rotation is positive and clockwise rotation along the axis of rotation is negative.
