temperaturesensor.java

这是一个以JAVA编写的程序,本人还没有试过,是一个简单的温度控制系统

package net.sf.dz.device.sensor;

import org.freehold.jukebox.conf.Configurable;

import net.sf.dz.event.TemperatureSensorListener;

/**
 * Dumb temperature sensor.

 * <p>
 *
 * Though dumb, the temperature sensor is an <strong>active</strong> entity,
 * not passive: it produces the temperature change notifications that drive
 * the rest of the system.
