The design of a low-power, high-resolution controller board for ?PnP

μPnP is a system that supports the plug-and-play integration of embedded sensors and actuators with the Internet of Things (IoT) [3]. The hardware element of μPnP uses passive electrical characteristics to identify embedded peripherals at orders of magnitude lower power than mainstream approaches such as USB or FireWire. This paper contributes a new design for the μPnP hardware element that achieves significant reductions in energy consumption and improvements in accuracy.
