Bridges serve as indispensable components of our infrastructure, known for their strength and durability. Yet, ensuring their ongoing safety demands attention to various factors, with deflection standing out as a critical indicator of structural health. Recognizing this imperative, this paper introduces an IoT (Internet of Things) based prototype device designed for remote deflection measurement in bridge structures. Through the integration of ultrasonic sensors and IoT technology, the device presents a comprehensive solution for continuous deflection monitoring. This approach not only facilitates proactive maintenance strategies but also enhances the overall resilience of bridges against unforeseen challenges. By harnessing the power of real-time data transmission and analysis, stakeholders can effectively identify and address potential issues before they escalate, thereby ensuring the lasting safety and integrity of bridge infrastructure. The efficacy and reliability of the prototype are underscored through experimental validation conducted on a meticulously crafted bridge model. These findings highlight the prototype’s potential for real-world deployment, showcasing its ability to revolutionize current practices in bridge maintenance and management. This IoT-enabled solution holds promise for safeguarding the longevity of bridge infrastructure, paving the way for a safer and more resilient future.
