SOIL MOISTURE SENSOR
WARF: P240275US01

Inventors: Bhuvana Krishnaswamy, Yoganand Biradavolu


The Invention
UW-Madison researchers have developed a battery-less tag that can harvest energy from radio signals above ground and send an active response, which is used to estimate the soil moisture. There are two parts, a battery-less tag design, and a sensing mechanism using energy harvesting and time to communicate soil moisture. The solution is low-cost using active radios and an RF source to estimate soil moisture at varying depths for in-situ measurement.
