Abstract
We present the design of an RFID-based passive sensor for pervasive soil moisture monitoring. Permittivity of soil changes with variations in moisture content causing a controlled change in the signal response of an RFID tag. We demonstrate that the passive sensor can reliably detect soil moisture content over a read distance of at least 0.8 m. Future research directions and prospective design improvements are also discussed.
