IoT power: battery, wired or wireless?
The term “Internet of Things” can be used to describe a huge range of different technologies, from sensors to gateways to back-end systems that organize data and keep machine-to-machine networks secure. Lots of attention is rightly paid to the way IoT systems gather data and how it moves from place to place. However, for some parts of the IoT, the issue of how to keep sensors powered may be just as important.
Particularly in the case of IoT systems that feature small sensors and sensors that might be far away from each other or from the rest of the system, energy usage is a critical concern, because traditional wired power may simply not be an option.
