The problem
Over-irrigation wastes water and power while under-irrigation cuts yield. Small plots cannot justify expensive commercial controllers.
What to build
Design a low-cost controller that reads soil moisture sensors, checks the weather forecast and switches a pump on a schedule that saves water without hurting the crop.
Success looks like
Demonstrate at least 25% water saving versus a fixed timer on a test plot, with remote override from a basic phone.
Suggested technologies
- ESP32
- Soil moisture sensors
- MQTT
- Weather API
- Rule-based control
