public class TemperatureSensor

extends java.lang.Object

This class acts as a wrapper around a temperature sensor. Whenever the temperature sensor changes by more than 0.5 degrees, the temperature, the units, and the timestamp are stored and made available to the context-aware infrastructure for polling, and can notify context widgets when data changes.

Constructor Detail

TemperatureSensor

public TemperatureSensor(Widget widget)

Constructor that allows this object to read data from the serial port to which the temperature sensor is connected. It sets the context widget to notify when there's a temperature change greater than THRESHOLD

Parameters:

widget - Widget to notify when the temperature changes greater than THRESHOLD
