Manhole Management System: IoT-Powered Solution for Safety and Efficiency

Abstract

The Manhole Management System is an IoT-based solution designed to enhance safety and efficiency in manhole monitoring. Real-time monitoring is crucial due to risks such as hazardous gas accumulation, flooding and overheating. This projects integrates IoT technologies to monitor air quality, water levels and temperature using the MQ-135 gas sensor, HC-SR04 ultrasonic sensor and LM35 temperature sensor with connected to an ESP32 microcontroller. When hazardous conditions are detected, the system demonstrates effective sensor integration, data processing and alerting with LEDs providing visual indicators and Telegram notifications ensuring timely warnings. So, the result confirm the system's ability to accurately detect hazards, improving safety and supporting efficient manhole management.
