A novel time domain reflectometry based chipless RFID soil moisture sensor

This Study focuses on the design and analysis of a novel low cost time domain reflectometry (TDR) based soil moisture sensor. This type of sensor enables to employ an efficient irrigation system for agricultural sector by obtaining accurate information about soil moisture profiles. The dielectric properties of the proposed sensor vary with volumetric water content of soil which instigates a variation in the sensor's TDR amplitude level. A critical analysis on the feasibility of the designed sensor is carried out here along with an experimental validation of a developed prototype.
