Working Flow

IoT Device Connects & Sends Data
→ Devices (simulated via Arduino/Raspberry Pi) send readings via MQTT to backend
Data Validation & Smart Contract Recording
→ Backend relays data to smart contracts for validation
→ Validated data stored immutably on blockchain
Dashboard Updates
→ Admin & device dashboards display real-time IoT readings and blockchain logs
Alerts & Notifications
→ Smart contracts trigger alerts for threshold violations or anomalies
Audit & Transparency
→ All device data and alerts stored on blockchain for verification
