Realtime Monitoring & Custom Alerting

Live lab telemetry with Grafana-style monitoring and MQTT routing.

Sensor measurements can be published over MQTT, centralized, visualized in realtime, and evaluated against custom alert rules. This demo simulates a small laboratory monitoring stack with updating telemetry, triggered alerts, and message routing.

Why centralize?

Elementary measurements become reusable infrastructure.

A temperature or humidity reading starts as a simple sensor value. Publishing it to MQTT creates a consistent event stream that can be consumed by Grafana, persisted for historical analysis, checked against custom thresholds, forwarded into a LIMS, used to trigger maintenance workflows, or exposed to other applications through APIs. The same measurement can support many systems without manual duplication.
