Abstract

A novel embedded sensing and wireless relay mote that powers itself from long range digital TV signals is presented. With an improved antenna, RF-DC circuit, and an energy-aware embedded-firmware design, enough wireless power from a distributed TV tower network can be harnessed for wireless sensor telemetry. A microcontroller and 900 MHz transmitter for the telemetry has been powered on and sustained from ambient TV signals at previously unreported range of 6.5 km from a TV broadcast source.

一个自我维持的，自主的，无线传感器信标，由远程，环境，射频能量供电

提出了一种利用远程数字电视信号为自身供电的新型嵌入式传感和无线中继模。通过改进的天线、RF-DC电路和能量感知嵌入式固件设计，可以利用来自分布式电视塔网络的足够无线功率进行无线传感器遥测。用于遥测的微控制器和900兆赫发射机已经通电，并从电视广播源以前未报告的6.5公里范围内的环境电视信号中维持。
