Abstract

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.

超高频射频识别在地下土壤传感器中的可行性研究

进行了一项研究，以评估使用超高频(UHF)射频识别(RFID)与地下传感器通信的可行性。结果表明，当读取器在FCC限值附近工作时，当土壤湿度水平为重量的15%或更低时，传感器的读取范围大于半米。在15%或更高的湿度水平导致显著衰减或信号完全丢失。标签还具有理想的读取范围，深度可达15厘米。
