Sensor List in Samsung GT-I9300

问题:

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.

'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.

Don't know if it helps, but you can install an app called "Elixir" which lists the sensors on the device. You can search for it on the Play Store.
