Embedded Sensor-based Construction Health Warning System for Civil Structures & Advanced Networking Techniques using IoT

Most civil constructions inside cities, such as flyovers and bridges, remain prone to damage as they are being used after their lifespan has ended which creates a threat to people who use it. Due to the large number of automobiles on the road in a populated city, bridges may collapse, resulting in a huge calamity. As a result, those bridges must be constantly monitored. In this paper, a model that comprises of a load sensing element, an arduino microcontroller, ac flux sensor, an infrared sensor, a Wi-Fi module, and a vibration sensor has been designed. This technology analyzes vibration, bridge bending and vehicle loads, and generates the alarm through buzzer, if the vehicle load, vehicle count, and bending of the bridge exceed the threshold level. Whenever necessary, an administrator delegates an assignment to the employees as upkeep. This communication between administration and the monitoring system is accomplished via the use of IoT. For future data analyses, a webapp is built with statistics acquired by the help of sensors.
