Autonomous Soil-Moisture Irrigation Controller
We built a self-contained irrigation system that reads soil moisture and waters the plant automatically when it dries out: battery-powered, fully on-device, with no Wi-Fi, app or cloud.

The problem
Plants die from inconsistent watering, and manual irrigation is unreliable for people who travel or keep many plants. Commercial smart-irrigation systems are expensive and over-engineered for small-scale use.
Solution & architecture
A complete closed-loop irrigation system built for under $8. No Wi-Fi, no app, no cloud; it reads soil moisture, decides when to water, and acts entirely on-device. Portable power-bank operation means it deploys anywhere (balconies, rooftops, remote farms) without mains electricity, with hysteresis to prevent rapid pump cycling.
Why it is built this way
Reads, decides, acts on-device
No Wi-Fi, app or cloud
Deploy anywhere
Battery-powered, no mains needed
Closed-loop
Hysteresis prevents pump chatter
