A study was performed to assess the viability of using ultra-high frequency (UHF) radio
frequency identification (RFID) to communicate with subsurface sensors. The results showed
that, when the reader operated near the FCC limit, read ranges for the sensorwere greater
than a half meter for soil moisture levels of 15% by weight or less. Moisture levels at 15% or
greater resulted in significant attenuation or complete loss of signal. Tags also had
desireable read ranges for depths up to 15 cm.
