ECO-SHIELD
ECO — Ecological · SHIELD — Smart Hazard Intelligence & Environmental Local Detection
From distributed sensing to validated risk and actionable warning.
Demonstration build — all readings, sites and alerts are simulated. No live field data is shown.
Three hazards run in the demo network; further hazards are additional pods on the same core.
Flood
Water level, rainfall and neighbor corroboration along river corridors.
In demo network
Fire
Smoke, heat and camera verification in forest belts.
In demo network
Air pollution
PM2.5 / PM10 across urban airsheds.
In demo network
Landslide
Terrain module supported by the architecture.
Architecture-ready
Water quality
Additional pod type on the same universal core.
Architecture-ready
REPLACEABLE SENSOR PODS
Hydro / Flood · Fire / Air
UNIVERSAL CORE
ESP32-S3 · Wio-E5 · LiFePO4 · Solar · IP65
CONFIGURABLE MULTI-HAZARD NODE
Swap a pod, keep the core
AI-0
Node intelligence
EWMA / Kalman smoothing, CUSUM shift detection, TinyML anomaly checks and sensor-health scoring on the node itself — useful even with no connectivity.
AI-1
Edge intelligence
Isolation Forest, XGBoost, GRU and vision models at the gateway, fused with reliability weights and gated by quorum.
AI-2
Cloud / regional intelligence
Regional risk, analytics, alert engine with de-duplication, and a model registry with human approval.
Severity and confidence are separate. One abnormal source is only suspicious; corroboration confirms; a faulty sensor is down-weighted.
Stewardship is a proposed community / institutional O&M model — no automatic government ownership or funding is assumed.
Select a stage to see its modules.
LoRa receiver / packet forwarder
Receive node uplinks and hand them to the edge runtime.
Raspberry Pi 4/5 + LoRa concentrator
Multi-model inference
Run complementary models: anomaly, hazard class, temporal escalation, vision.
Isolation Forest · XGBoost · GRU · RTMDet · MobileNetV3-Small
Evidence fusion
Combine sensor, model, camera, neighbor and weather evidence with reliability weights.
E = Σ(wᵢ × eᵢ) / Σwᵢ
Quorum-gated validation
Require multi-source corroboration; suppress single faulty sensors.
Rule engine
Risk + confidence
Publish severity and confidence as separate axes.
Threshold policy (demo-configured)
Local response
Trigger siren / notice board without any cloud connectivity.
GPIO / relay
ECO-SHIELD is decision support, not an autonomous emergency command. Demonstration data is simulated.
