Precision Irrigation for Vineyards
summary
System measures soil water potential that correlates with plant stress, uses cheap custom probes aiming for a $15 sensor target, and vertical arrays (recommendation: three sensors at 2/3/4 ft) to keep water in the active root zone. Network runs on Arduino nodes and LoRa gateways (single gateway line‑of‑sight ~6 miles), about 50 nodes deployed, 140 growers in the network, units run continuously for two years, and field trials report a reproducible 50% water reduction while an automated valve controller (up to five valves) is being released.
