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 networks by making them difficult and expensive to install and maintain.Battery.powered wire1ess 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 environments.To facilitate the wide-spread 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 make the best 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.
According to the passage,Greenpeak__________.
选项
A、is the first company to install wireless sensor networks
B、promotes the application of wireless sensor networks
C、supplies batteries operating on harvested energy
D、benefits handsomely from communication technology
答案
B
解析
推断题。根据第四段第三句可知,为了方便无线传感器网络广泛部署,Greenpeak已经开发出一种超低功耗的通信技术,该技术能够利用环境中的光、运动和震动之类的能源。故本题选B。
