```
public class WifiSensor
extends Sensor
```
This class provides an implementation of sensor API for detecting currentlu active Wifi network. WifiSensor is a subclass of the abstract base class Sensor. It uses Android WifiManager API to detect the current Wifi and changes in network state. It detects the ssid of the current, connected Wifi (if any).
