Sensor List in Samsung GT-I9300

Please help.I am trying to get all the available sensors of a android device.But when i tried to get from 'GT_19300' it shows a list given below

      "LSM330DLC 3-axis Accelerometer
      AK8975C 3-axis Magnetic field sensor
      iNemoEngine Orientation sensor
      CM36651 Light sensor
      CM36651 Proximity sensor
      LSM330DLC Gyroscope sensor
      iNemoEngine Gravity sensor
      iNemoEngine Linear Acceleration sensor
      iNemoEngine Rotation_Vector sensor
      LPS331AP Pressure Sensor
      Rotation Vector Sensor
      Gravity Sensor
      Linear Acceleration Sensor
      Orientation Sensor
      Corrected Gyroscope Sensor"

I am feeling that the list has some repeat names. I want to know that is this all sensors available in GT_19300 or is it a repetition.If i am using the Gyroscope Sensor which one i want to use. Please share your valid answers.

Solution

'iNemoEngine xxx' should be a kind of 'virtual sensor', like 'rotation_vector sensor' implemented in ICS by Google.

Accelerometer, Magnetic, Light, Proximity, Gyroscope, Pressure, Gravity, these are hardware-sensor.

others like linear accerlerometer, rotation vector, orientation, these are software implemented using sensor fusion algorithm.

you dont need to care about these names but try:

public void onSensorChanged(SensorEvent event) {
    switch(event.sensor.getType()) {

             case Sensor.TYPE_GYROSCOPE:
             // 
             // your processing
             break;
            }
     }

for gyroscope on S3, I believe you will receive data from 'LSM330DLC Gyroscope sensor'.

hope this will help.
