将能量收集资源连接到物联网的电源
本文着眼于能源的不同方式可以收获的能源传感器节点的物联网。它着眼于不同的技术从振动的热功率和能量的方式可提供传感器和无线节点链路的数据到互联网，和评估工具，可以帮助开发公司如EnOcean这样的系统，先进的线性器件，Cymbet和崔。
权力是物联网的重要商品。更低的功耗意味着更小的尺寸，使传感器节点和网关可以放置在更方便的位置，从较小的电池的成本更低，和更少的冷却。
随着数以百万计的传感器节点，更换电池的时间和成本是巨大的，和任何功率减少产生效益，延长更换周期。这是一个关键的限制，推出的无线传感器节点连接在一起，创造物联网。
能量收集技术可以帮助延长电池之间的时间，通过充值充电设备，甚至消除它们一起，仅仅使用它们来平滑的电力输送到电子。
The move to energy harvesting has been boosted by developments in several areas. The power consumption of sensors， microcontrollers and wireless transceivers has fallen dramatically over the last few years as more efficient silicon technology has been available and more efficient wireless protocols such as ultra-low-power ZigBee with lower duty cycles have been more widely available.
At the same time， the efficiency of certain energy-harvesting technologies such as solar cells has improved considerably， and the costs have come down， allowing them to be used in high volume applications such as the Internet of Things. A key element of the increasing penetration of energy harvesting into these applications is the use of a new generation of power controllers such as the EH4205 step-up low-voltage booster module from Advanced Linear Devices， which can handle the low currents from the energy sources and manage the fluctuations to provide a reliable power flow to the electronics.
