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.
