ZigBee：无线技术，低功耗传感器网络(中文5700字,英文3000字)
技师（工程师）们在发掘无线传感器的潜在应用方面从未感到任何困难。例如，在家庭安全系统方面，无线传感器相对于有线传感器更易安装。而有线传感器装置布线的花费通常占无线传感器安装费用的80%的工业环境方面也是同样适用。而且在有线传感器的不适合甚至是不能使用的领域，无线传感器更具应用性。
虽然，无线传感器需要消耗更多能量，也就是说所需电池的数量会随之增加或充电过于频繁。再加上对无线传感器经空气传送数据可靠性的怀疑，所以无线传感器看起来并不是那么吸引人。
一个低功率无线技术被称为ZigBee，它是无线传感器技术的革新。但是，一个安全的网络技术，对最近通过的IEEE 802.15.4无线标准（图1）的顶部游戏机，ZigBee承诺把无线传感器应用到从工厂自动化系统、家庭安全系统到消费电子产品的一切领域。与802.15.4的合作下，ZigBee使用的电池寿命可比普通小型电池的长几年。 ZigBee设备的价格预计也比较便宜，有人估计销售价格最终不到3美元每节点。由于价格低，他们自然适应用在于如无线光线开关，无线自动调温器，烟雾探测器等家用产品。

ZigBee: Wireless Technology for Low-Power Sensor Networks
Technologists have never had trouble coming up with potential applications for wireless sensors. In a home security system, for example, wireless sensors would be much easier to install than sensors that need wiring. The same is true in industrial environments, where wiring typically accounts for 80% of the cost of sensor installations. And then there are applications for sensors where wiring isn't practical or even possible.
The problem, though, is that most wireless sensors use too much power, which means that their batteries either have to be very large or get changed far too often. Add to that some skepticism about the reliability of sensor data that's sent through the air, and wireless sensors simply haven't looked very appealing.
A low-power wireless technology called ZigBee is rewriting the wireless sensor equation, however. A secure network technology that rides on top of the recently ratified IEEE 802.15.4 radio standard (Figure 1), ZigBee promises to put wireless sensors in everything from factory automation systems to home security systems to consumer electronics. In conjunction with 802.15.4, ZigBee offers battery life of up to several years for common small batteries. ZigBee devices are also expected to be cheap, eventually selling for less than $3 per node by some estimates. With prices that low, they should be a natural fit even in household products like wireless light switches, wireless thermostats, and smoke detectors.
