TerraSync

Sensor-driven automated irrigation system monitoring real-time soil moisture levels and triggering a water pump when soil dries below a configurable threshold. Battery-powered, fully self-contained for homes, balconies, and small-scale farms.

TerraSync
// overview

A complete closed-loop irrigation system built for under $8. No Wi-Fi, no app, no cloud. Reads soil moisture, decides when to water, and acts entirely on-device. Portable power bank operation for deployment anywhere.
