Elevated Gardening with the Kotlin Ecosystem
summary
A home Rice Garden gets instrumented into a networked hydroponic controller that measures pH and ppm every minute, doses milliliter volumes with peristaltic pumps, and uploads readings via a Raspberry Pi to a Spring Boot server on DigitalOcean running WebFlux and coroutines. Sensors are Atlas Scientific, data lands in MongoDB time-series collections, Android and web UIs use Jetpack Compose sharing Kotlin data models. The system runs in Docker, automates dosing, and has produced lettuce and strawberries.
