IoT – Enabled Smart Bridge Control with Node MCU ESP8266

Abstract

The increasing demand for intelligent infrastructure has led to the development of automated systems capable of enhancing safety, efficiency, and reliability in bridge operations. This research presents the design and implementation of an Advanced Bridge Control System using embedded technology, specifically centered on the Arduino Uno microcontroller. The system integrates a range of sensors, actuators, and wireless communication modules to monitor environmental and traffic conditions and automatically control the opening and closing of a movable bridge. The project aims to reduce human intervention, improve response time during high traffic or emergency scenarios, and ensure structural integrity through real-time data collection. Key features include obstacle detection, automated barriers, warning systems, and remote control capability. This low-cost, scalable solution demonstrates how embedded systems and IoT components can be effectively used to modernize critical infrastructure. Simulation results and prototype testing confirm the system's functionality and potential for real-world deployment in smart city environments.
