Access temperature sensor, TYPE_TEMPERATURE and TYPE_AMBIENT_TEMPERATURE.

The temperature sensors (Sensor.TYPE_TEMPERATURE/Sensor.TYPE_AMBIENT_TEMPERATURE) are used to determine temperature of the phone, for internal hardware. They are not available on all device. (It's not available on my HTC One X and HTC Flyer!)

Sensor.TYPE_TEMPERATURE is deprecated, use Sensor.TYPE_AMBIENT_TEMPERATURE instead.

Example:

package com.example.androidsensor; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; import android.app.Activity; import android.widget.TextView; public class MainActivity extends Activity { TextView textTEMPERATURE_available, textTEMPERATURE_reading; TextView textAMBIENT_TEMPERATURE_available, textAMBIENT_TEMPERATURE_reading; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textTEMPERATURE_available = (TextView)findViewById(R.id.TEMPERATURE_available); textTEMPERATURE_reading = (TextView)findViewById(R.id.TEMPERATURE_reading); textAMBIENT_TEMPERATURE_available = (TextView)findViewById(R.id.AMBIENT_TEMPERATURE_available); textAMBIENT_TEMPERATURE_reading = (TextView)findViewById(R.id.AMBIENT_TEMPERATURE_reading); SensorManager mySensorManager = (SensorManager)getSystemService(SENSOR_SERVICE); Sensor TemperatureSensor = mySensorManager.getDefaultSensor(Sensor.TYPE_TEMPERATURE); if(TemperatureSensor != null){ textTEMPERATURE_available.setText("Sensor.TYPE_TEMPERATURE Available"); mySensorManager.registerListener( TemperatureSensorListener, TemperatureSensor, SensorManager.SENSOR_DELAY_NORMAL); }else{ textTEMPERATURE_available.setText("Sensor.TYPE_TEMPERATURE NOT Available"); } Sensor AmbientTemperatureSensor = mySensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE); if(AmbientTemperatureSensor != null){ textAMBIENT_TEMPERATURE_available.setText("Sensor.TYPE_AMBIENT_TEMPERATURE Available"); mySensorManager.registerListener( AmbientTemperatureSensorListener, AmbientTemperatureSensor, SensorManager.SENSOR_DELAY_NORMAL); }else{ textAMBIENT_TEMPERATURE_available.setText("Sensor.TYPE_AMBIENT_TEMPERATURE NOT Available"); } } private final SensorEventListener TemperatureSensorListener = new SensorEventListener(){ @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { // TODO Auto-generated method stub } @Override public void onSensorChanged(SensorEvent event) { if(event.sensor.getType() == Sensor.TYPE_TEMPERATURE){ textTEMPERATURE_reading.setText("TEMPERATURE: " + event.values[0]); } } }; private final SensorEventListener AmbientTemperatureSensorListener = new SensorEventListener(){ @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { // TODO Auto-generated method stub } @Override public void onSensorChanged(SensorEvent event) { if(event.sensor.getType() == Sensor.TYPE_AMBIENT_TEMPERATURE){ textAMBIENT_TEMPERATURE_reading.setText("AMBIENT TEMPERATURE: " + event.values[0]); } } }; }
