getting the temperature of environment in an android program

My phone in Huawei g600 and I don't get the temperature sensor in the list of all sensors in my program, but I need the temperature of environment in my application, Does any one has a solution?

 List<Sensor> list = sMgr.getSensorList(Sensor.TYPE_PRESSURE);

StringBuilder data = new StringBuilder();
for(Sensor sensor : list){
   data.append(sensor.getName() + "\n");

 }
sensorslist.setText(data);

I appreciate it's an old question but I looked into this too. There is a way you can get a good approximation of the outside temperature, from your battery temperature.

In general the formula:

Te = (m *Tc) + k

works.

  • Te (external temperature)
  • m (local modifier)
  • Tc (Battery temperature)
  • k (-60.522)

For London, for example, m is 2.55 and is dependant on the time of year (summer Vs winter).

Not all (in fact almost none) devices have an external temperature sensor. Its rare hardware and even was discouraged by Google for a while. The reason is that phones run hot- the battery can easily get hot enough to burn. That means any thermometer will be inaccurate. You're better off with either local weather date via web service, or using a usb or bluetooth device connected to your phone to take temperature. Even if you find a device with a temperature sensor you can't trust its accuracy, for the reasons stated above.
