TerraGrow: Integrated platform for real time plant monitoring and automated watering system with IoT and fuzzy Sugeno Algorithm

Global water scarcity, climate variability, and rising input costs are pushing agriculture toward precise, evidence-based irrigation, yet many available systems remain proprietary, expensive, and difficult to adapt. TerraGrow is an open-source, low-cost controller that runs all sensing and closed-loop irrigation locally on a single ESP32, using real-time soil moisture, pH, temperature, and humidity inputs with a Sugeno-type fuzzy policy. Its modular and ergonomic hardware with a printable enclosure, integrated pump driver, and labeled connectors lets non-experts assemble, calibrate, and service the unit quickly in the field. Compared with earlier low-cost IoT irrigation nodes, TerraGrow's novelty lies in fully local multi-sensor fuzzy control and an easy-to-deploy form factor supported by complete and reproducible design files. Bench and greenhouse tests showed stable moisture regulation and reduced unnecessary watering, enabled by precise sensing and a consistent hardware and firmware implementation. By combining local autonomy, simple deployment, and open documentation, TerraGrow makes practical precision irrigation more accessible to resource-constrained growers.
