Subterranean Access Point Surveillance System

The Subterranean Access Point Surveillance System (SAPSS) is a comprehensive solution designed for monitoring and managing manholes in urban sewer systems. SAPSS integrates advanced technologies, including sensors, microcontrollers, and communication modules, to provide real-time data on water levels, gas emissions, vibrations, and debris accumulation. By detecting abnormalities early, SAPSS enables proactive maintenance, minimizing the risk of costly damages and ensuring the integrity of sewer systems. The system consists of an ESP32 microcontroller, waterproof ultrasonic sensor, MQ2 gas sensor, tilt sensor, GSM module, boost module, mesh frame with a servo motor, and ThingSpeak integration for real-time data monitoring and analysis. The ESP32 serves as the central processing unit, interfacing with the various sensors and modules to collect and process data. The GSM module enables SAPSS to send real-time alerts to maintenance personnel, ensuring prompt action in case of abnormalities. Implementation of SAPSS involves programming the ESP32 microcontroller using the Arduino IDE and integrating the sensors and modules for data collection. The system prototype is highly scalable, allowing for additional sensors and modules to be added for more comprehensive monitoring. The feasibility of SAPSS is supported by the availability of off-the-shelf components and the relatively straightforward integration process. Overall, SAPSS offers a comprehensive and innovative solution for monitoring and managing manholes in urban sewer systems, enabling proactive maintenance and ensuring the sustainability of urban infrastructure.
