基于自供電開(kāi)關(guān)的超低功耗ZigBee傳輸

　　設(shè)計(jì)與能源收集來(lái)源一起使用的ZigBee應(yīng)用程序提出了一些挑戰(zhàn)。最難使用的礦車(chē)之一是自發(fā)電開(kāi)關(guān)，因?yàn)楫a(chǎn)生了少量的能量。利用超低功耗單片機(jī)Jennic JN5148，它是可能的設(shè)計(jì)工作中的應(yīng)用從SPS驅(qū)動(dòng)，可以實(shí)現(xiàn)三基于ZigBee技術(shù)的變速器只使用100 UJ能量。

　　Energy harvesting as a method of power generation for wireless sensors introduces the potential for a sustainable wireless sensor networking solution， enabling key concerns with ongoing maintenance costs and the environmental issue of battery disposal to be addressed.

　　Use of the high-performance 32-bit RISC CPU core inside the JN5148 for fast processing， combined with the ultra-low-power consumption of the device in sleep and when active， enables designers to use energy levels that might ordinarily be considered as insignificant to generate sufficient power to energize the ultra-low-power Jennic microcontrollers.

　　Jennic recently partnered with a number of energy harvesting providers and is focused on utilizing sustainable power sources for standards based wireless sensor networks.
