最小化物联网传感器节点功耗
由于有数十亿的物联网传感器节点尚未部署，许多传感器节点开发面临的关键问题是电源。运行这些传感器的电力线是不切实际的，由于他们的位置，即使可行的，费时和昂贵的。
此外，维修和更换电池可以大大降低业务案例。产品设计者需要要么无限延长电池寿命，要么寻找替代设备来驱动他们的设备。
本文将介绍如何分析一个产品的功耗和优化其硬件和软件，然后讨论如何增加电池与最新的能量收集技术。
The energy profile
The key feature that designers need to examine and opTImize is the energy profile for their product. The energy profile consists of：
Dynamic energy consumpTIon： The energy consumed when the device is awake and operaTIng
StaTIc energy consumption： The energy consumed while the device is sleeping and not performing any work.
Designers have at least three options available that can be used to extend their battery life and minimize system maintenance：
Hardware energy optimization
Software energy optimization
Energy harvesting
