Smart Irrigation & Soil Salinity Telemetry via Time-Domain Reflectometry (TDR)
High-frequency electromagnetic wave probe measuring soil dielectric permittivity to measure moisture and salinity independently.
Project Overview
Surpasses cheap resistive soil probes that corrode rapidly. Launches high-frequency pulses down stainless-steel wave-guide prongs, measuring pulse transit reflection times to measure volumetric water content (VWC) and electrical conductivity (EC) accurately across varying soil types.
