Temperature sensor stub

This stub code realizes an interface to a temperature sensor. It uses the generic sensor interface that provides access to a single value.

The ISensor interface defines common interface functions to access a sensor.

1. /**

2.  * The sensor interface enables reading of one sensor value

3.  */

4. public interface ISensor {

6. 	public double readValue();

8. }

The TemperatureSensor stub is used during the example. It implements a very basic simulation model for the oven temperature.

1. /**

2.  * A sensor for reading a temperature value that is dependent on a heater

3.  */

4. public class TemperatureSensor implements ISensor {

5. 	private final double maxTemperature = 50;

6. 	private final double minTemperature = 20;

7. 	private final double changeRate = 0.1d;

9. 	private double currentTemperature = 20.0;

11. 	public TemperatureSensor(final Heater heater) {

13. 		// Start a new Thread that updates the temperature in every tick

14. 		new Thread(() -> {

15. 			while (true) {

16. 				try {

17. 					Thread.sleep(100);

18. 				} catch (InterruptedException e) {

19. 					e.printStackTrace();

20. 				}

21. 				double targetTemperature = minTemperature;

22. 				if (heater.isActive()) {

23. 					targetTemperature = maxTemperature;

24. 				}

25. 				currentTemperature = (1 - changeRate) * currentTemperature + changeRate * targetTemperature;

26. 			}

27. 		}).start();

28. 	}

30. 	public double readValue() {

31. 		return currentTemperature;

32. 	}

33. }
