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;

textTEMPERATURE_available

SensorManager mySensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);

if(TemperatureSensor != null){
textTEMPERATURE_available.setText("Sensor.TYPE_TEMPERATURE Available");
mySensorManager.registerListener(
TemperatureSensorListener,
TemperatureSensor,

}
Sensor AmbientTemperatureSensor

textAMBIENT_TEMPERATURE_available.setText("Sensor.TYPE_AMBIENT_TEMPERATURE Available");
mySensorManager.registerListener(
