The automation of height-increasing bridges during floating events is a crucial engineering challenge in areas prone to flooding or water surges. It proposes a solution to adjust the bridge height automatically based on real-time data obtained from an ultrasonic sensor and processed using an Arduino microcontroller. The objective of this research is to create a mechanism that can dynamically modify the bridge's height in response to rising water levels, protecting both cars and pedestrians. The system comprises an ultrasonic sensor mounted on the bridge structure, an Arduino is used for processing the data and decision-making, and an actuator mechanism for bridge elevation control. The ultrasonic sensor is used to measure the gap between the sensor and the surface of the water. By monitoring the water level perpetually, the sensor provides accurate and reliable data to the Arduino board. The Arduino board, programmed with appropriate algorithms, analyzes the sensor readings and determines the appropriate action has to be undertaken. The Arduino microcontroller processes the data that has been collected and then it uses advanced algorithms for analysis and decision-making. This enables proactive maintenance and the early detection of any potential issues that may compromise the bridge's safety or structural integrity. It advances smart infrastructure solutions to enhance disaster robustness and public safety.
