Abstract Billions of Radio-Frequency Identification (RFID) passive tags are produced yearly
to identify goods remotely. New research and business applications are continuously …

This work proposes a novel soil environment monitoring system based on RFID sensor and
LoRa to realize long term and low cost monitoring. The monitoring system consists of patrol …

A farm's soil moisture and soil electrical conductivity (EC) readings are extremely valuable
for a farmer. They can help her reduce water use and improve productivity. However, the …

This survey provides an overview of recent advancements in wireless soil sensing
technologies, including the sensors and communication systems used to manage and …

Two solutions for UHF RFID tags for soil moisture sensing were designed and are described
in this paper. In the first, two conventional tags (standard transponders) are employed: one …

In this paper, we present the design, fabrication and calibration of a passive UHF RFID tag
based soil moisture and environment temperature sensor. The inter-digital double-sided …

Transportation infrastructure experiences distress due to aging, overuse, and climate
changes. To reduce maintenance costs and labor, researchers have developed various …

In this work, it is proposed the integration of a time-domain transmissometry soil moisture
sensor with a fully passive UHF RFID tag. A coplanar waveguide based sensor is modeled …

This study focuses on the electromagnetic characterization of a novel low cost UHF RFID
sensor for soil moisture and salinity content detection. A theoretical model of soil with …

This paper presents a system to estimate soil moisture through the reading of standard Ultra
High Frequency (UHF) passive RFID tags that can be buried in the soil, allowing wireless …
