Method Detail

init

protected void init()

getAccelerationMode

public SensorMode getAccelerationMode()

HiTechnic NXT Acceleration , Acceleration mode
Measures acceleration over three axes.

Size and content of the sample
The sample contains 3 elements, containing acceleration over the X, Y and Z axis respectively. The range of the sensor is -2 to 2 G (1G = 9.81 m/s²).

Returns:

A sampleProvider See leJOS conventions for SampleProviders See Sensor datasheet
