This project presents the design and implementation of a rain-operated manhole system tailored for smart cities. The proposed system integrates various sensors including rain, water flow, tilt, MQ2 gas, and temperature sensors along with GSM communication, LCD display, and a buzzer. The rain sensor detects precipitation, triggering the opening of the manhole cover to prevent flooding during heavy rainfall. Water flow and tilt sensors ensure efficient drainage and detect any anomalies in the manhole's position. The MQ2 gas sensor monitors air quality within the manhole, providing early detection of hazardous gases. Temperature sensors help in assessing environmental conditions. Integration with GSM enables real-time communication for remote monitoring and control. An LCD display offers local feedback, while a buzzer provides audible alerts. This smart infrastructure solution contributes to the resilience and safety of urban environments, enhancing the efficiency of drainage systems and reducing the risk of flooding-related incidents in smart cities.
