The system variable pRotationY always contains the rotation of the device along the y axis in the frame previous to the current frame. If the sketch angleMode() is set to DEGREES, the value will be -90 to 90. If it is set to RADIANS, the value will be -PI/2 to PI/2.
pRotationY can also be used with rotationY to determine the rotate direction of the device along the Y-axis.
