You can use TYPE_AMBIENT_TEMPERATURE for battery or CPU temperature. TYPE_TEMPERATURE is the depcrecated constant.

The modified version of code available at documentation should be like this:

import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

public class TempSensorActivity extends Activity, implements SensorEventListener {
 private final SensorManager mSensorManager;
 private final Sensor mTempSensor;

 public TempSensorActivity() {
     mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
     mTempSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
 }

 protected void onResume() {
     super.onResume();
     mSensorManager.registerListener(this, mTempSensor, SensorManager.SENSOR_DELAY_NORMAL);
 }

 protected void onPause() {
     super.onPause();
     mSensorManager.unregisterListener(this);
 }

 public void onAccuracyChanged(Sensor sensor, int accuracy) {
 }

 public void onSensorChanged(SensorEvent event) {
 }
}

Look at sensor documentation for more.
