Edge Computing-based Intelligent Manhole Cover Management System For Smart Cities

This project proposes an edge computing-based intelligent manhole cover management system designed for smart city infrastructure, aiming to enhance public safety and maintenance efficiency. The system utilizes an Arduino as the central controller and integrates multiple sensors, including a gas sensor to detect the presence of hazardous gases, an ultrasonic sensor to monitor water levels inside the manhole, and an IR sensor to detect the status of the manhole lid (open or closed). These sensors enable real-time, on-site monitoring of potential dangers such as gas leaks, flooding, or unauthorized access. When any abnormal condition is detected—such as high gas concentration, rising water level, or an open lid—the system activates a buzzer for immediate local alert and sends a warning message via GSM to maintenance authorities. All sensor readings and alerts are also displayed on an LCD screen for local visibility. This intelligent system leverages edge computing for faster decision-making and provides a reliable, automated solution to improve urban safety and infrastructure management.
