Why is Temp: 0.0?
```auto
import ketai.sensors.*;
KetaiSensor sensor;
float temp;
void setup()
{
fullScreen();
sensor = new KetaiSensor(this);
sensor.start();
sensor.list();
orientation(LANDSCAPE);
textAlign(CENTER);
textSize(displayDensity * 28);
}
void draw(){
background(78, 93, 75);
text("Temp: " + temp, width/2, height/2);
}
void onTemperatureEvent(float tempe){
temp = tempe;
}
```

@Rogo === a lot of devices are without this sensor which is a physical one; so you have to ask wether it s available; if not change your phone add it this sensor…Another solution (which is a workaround!) coul be to get the temp from your geoloc through the web.
```auto
fullScreen();
sensor = new KetaiSensor(this);
sensor.start();
println("temp===="+sensor.isTemperatureAvailable());
```

@Rogo === excuse me, i have posted too quicly= if you want only to get the battery temp that is possible through android batteryManager but not with Ketai.[https://developer.android.com/reference/android/os/BatteryManager](https://developer.android.com/reference/android/os/BatteryManager)

@Rogo === that means that your phone has no (physical) sensor for ambient temperature, as it is possible for only few devices; but as i have written if you want only temperature for battery you can probably get it with batteryManager. Of course Ketai lib is absolutely useless for that. If necessary i can put code for that.

you can it may be possible that you phone doesnot have a temperature sensor in it !
I am not sure if ketai support battery temp since I used ketai long time ago !
You can see how to get battery temperature in android programatically [Stackoverflow/hget-battery-temperature-in-android](https://stackoverflow.com/questions/3997289/get-temperature-of-battery-on-android)
