Vinduino: An Open-Source, Affordable Water-Saving Technology - Electronic Design

The first generation of resistive soil-moisture sensors was a gypsum block sensor developed by Bouyoucos and Mick in the 1940s as part of government-funded research for improving agricultural efficiency during the Second World War. This basic design, two electrodes cast in a gypsum medium, was used as a low-cost alternative for expensive commercial sensors in the early stage of the Vinduino project. These sensors have held up well for several years in our Temecula vineyard, but their detection range starts at ‒55 kPa, which limits their usefulness to drought-tolerant crops.
