Environmental Monitoring — Solution Blueprint

Status: Experimental (scaffold) · Timeline: Later · Path: examples/solutions/environmental-monitoring/

Official Solution Blueprint for distributed sensor networks monitoring air, water, and environmental conditions.

Full roadmap entry: ROADMAP.md § Environmental Monitoring


Purpose

Deploy long-life battery sensor nodes with mesh telemetry, calibration gates, baseline drift detection, and cloud ingest for trend analysis and alerting.

Platform pillars used

Pillar Capabilities
Device & Fleet Device tree, health policies (battery, connectivity), OTA firmware
Operations Telemetry store, OTLP export, alerting, readiness trends
Packages & Ecosystem spanda-lora, spanda-mqtt, spanda-cellular, spanda-otel-collector
Verification Calibration readiness, assurance drift on baselines

Reference architecture (planned)

Sensor Network
├── Field nodes (LoRa / BLE)
├── Gateway (MQTT / cellular backhaul)
├── Edge readiness (calibration, battery require)
├── Telemetry store (JSONL / SQLite / OTLP)
└── Control Center dashboards + alert rules
