HydroGem

Environmental monitoring stations generate continuous data streams—pH, turbidity, dissolved oxygen, conductivity, and 8 more parameters. Most dashboards show numbers; HydroGem shows trends. The React + TypeScript system visualizes all 12 water quality parameters with 5-second auto-refresh, configurable alert thresholds, and historical trend comparison.

The dashboard supports multi-language (i18n) for deployment across regions, with responsive design for both control room displays and mobile field checks. Alert thresholds are configurable per parameter, triggering notifications before water quality degrades past regulatory limits. Built as an open-source reference for IoT environmental monitoring.
