IntelliBridge: A Low-Cost Offline Multi-Sensor Framework for Real-Time Bridge Health Risk Classification

Bridges are critical infrastructure, yet conventional visual inspections often fail to detect early structural deterioration. This paper proposes IntelliBridge, a cost-effective smart monitoring system using ESP32 and multiple sensors to observe structural parameters in real time. A threshold-based classification algorithm categorizes bridge conditions into Safe, Warning, and Danger, enabling early anomaly detection and improved structural safety.
