將能量收集資源連接到物聯(lián)網(wǎng)的電源

　　本文著眼于能源的不同方式可以收獲的能源傳感器節(jié)點(diǎn)的物聯(lián)網(wǎng)。它著眼于不同的技術(shù)從振動的熱功率和能量的方式可提供傳感器和無線節(jié)點(diǎn)鏈路的數(shù)據(jù)到互聯(lián)網(wǎng)，和評估工具，可以幫助開發(fā)公司如EnOcean這樣的系統(tǒng)，先進(jìn)的線性器件，Cymbet和崔。

　　權(quán)力是物聯(lián)網(wǎng)的重要商品。更低的功耗意味著更小的尺寸，使傳感器節(jié)點(diǎn)和網(wǎng)關(guān)可以放置在更方便的位置，從較小的電池的成本更低，和更少的冷卻。

　　隨著數(shù)以百萬計的傳感器節(jié)點(diǎn)，更換電池的時間和成本是巨大的，和任何功率減少產(chǎn)生效益，延長更換周期。這是一個關(guān)鍵的限制，推出的無線傳感器節(jié)點(diǎn)連接在一起，創(chuàng)造物聯(lián)網(wǎng)。

　　能量收集技術(shù)可以幫助延長電池之間的時間，通過充值充電設(shè)備，甚至消除它們一起，僅僅使用它們來平滑的電力輸送到電子。

　　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.
