Many are aware of the tremendous waste of energy in our environment, but fail to take advantage of straightforward opportunities to conserve that energy. For example, everyone knows that lights should be switched off when no one is in an office. Similarly, when employees are not using a meeting room, there is no need to regulate temperature.
Fortunately, one need not rely on human intervention to conserve energy. With the help of smart sensing and network technology, energy conservation processes such as turning off lights and adjusting temperature can be readily automated. Ultimately, this technology will enable consumers and plant managers to better identify wasteful energy use and institute procedures that lead to smarter and more efficient homes, buildings and industrial plants.
Until now, wires and cables for power and connectivity have limited the widespread adoption of sensor (传感器) networks by making them difficult and expensive to install and maintain. Battery-powered wireless networks can simplify installation and reduce cost. But their high power consumption and the corresponding need for regular battery replacement has made wireless networks difficult and costly to maintain. Nobody wants to replace hundreds or thousands of window sensor batteries in a large building on a regular basis.
The promise of wireless sensor networks can only be fully realized when the wiring for both the data communication and the power supply is eliminated. Doing so requires a true battery-free wireless solution, one that can utilize energy harvested directly from the environment.
To facilitate the widespread deployment of wireless sensor networks, GreenPeak has developed an ultra-low-power communication technology that can utilize environmental energy sources such as light, motion and vibration. This technology, employing on-board power management circuits and computer software to monitor energy harvesters and optimize (充分利用) the use of harvested energy, enables sensors to operate reliably in a battery-free environment.
Wireless sensor networks deployed in our offices and homes will have an enormous impact on our daily lives, helping to build a smarter world in which energy is recycled and fully utilized. These wireless platforms, equipped with advanced sensing capability, will enable us to better control our lives, homes and environment, creating a truly connected world that enables people worldwide to live in a more comfortable, safer, and cleaner environment. [br] Wireless sensor networks promise to______.
选项
A、further develop the sensing technology
B、turn motion into a major source of energy
C、improve the daily lives of people worldwide
D、bring businesses handsome profits in short time
答案
C
解析
末段首先提到无线传感器网络对我们的日常生活产生巨大的影响,帮助我们创建一个更智能的世界,随后进行了解释:这些无线平台能够让我们更好的控制我们的生活、家庭和环境,创建一个真正的互联世界,让全世界的人们能够生活在更舒适、更安全、更干净的环境中。由此可知,无线传感器网络能够提高全世界人们的日常生活质量,故答案为[C]。[A]和[D]在文中未提及,故排除。将motion转化为能源是GreenPeak研发的communication technology的作用,并不是无线传感器网络的目标,故排除[B]。
