I´m trying to read the values of the Light Sensor of my Nexus One, but I´mgetting only following values:
10.0
225.0
and in a few cases some values much higher.
The used code:
sensorManager = (SensorManager) context
.getSystemService(Context.SENSOR_SERVICE);
sensor = sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
listener = new SensorEventListener() {
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
@Override
public void onSensorChanged(SensorEvent event) {
Log.d(Constants.TAG, "Brightness: " + event.values[0]);
}
};
sensorManager.registerListener(listener, sensor,
SensorManager.SENSOR_DELAY_NORMAL);
}
Does anybody have experience with the light sensor on the Nexus One or another Android device? Is my code the correct way to read the values? How can I get better and more accurate values?
Your code looks fine. I was receiving values like this: 10, 225, 320, 640, 1280, 2600, 3200, 10240. But I really needed to point device towards sun to receive higher values.
Edit: from light sensor characteristic that can be obtained on my phone by using Android API - 10240 is the highest value that can be returned by this sensor.
