Observability Made Simple: Monitoring Plants with IoT & Grafana
summary
Built a soil‑moisture monitor using an ESP32 devkit, Arduino IDE and a moisture probe that reads analog values every 5s, sends metrics via the Prometheus Arduino library to a managed Prometheus instance on Grafana Cloud, and visualizes with Grafana dashboards (gauge/stat/time‑series) with a threshold at 500 that triggers Telegram alerts. Project runs, keeps houseplants healthy, and includes code on GitHub and plans to add automated watering.
