Design of ESP32-Based Smart Urban System for Automated Water Level Monitoring and Efficient Energy Management

Abstract

The rapid growth of urban populations and smart city initiatives has increased the demand for efficient urban utility management systems, with over 55% of the global population living in cities and municipal inefficiencies causing nearly 20–30% resource wastage annually, while IoT-based smart city solutions are projected to grow at over 19% annually. Additionally, issues such as water overflow, inefficient streetlight operation, and manual pump control contribute to energy loss, safety hazards, and increased operational costs. Traditional urban utility management systems rely heavily on manual monitoring and fixed schedules, which often lead to delayed responses, water wastage, overflow incidents, and inefficient energy consumption. Furthermore, conventional systems lack realtime data visibility, remote accessibility, and automated control mechanisms, reducing their effectiveness in dynamic urban environments. To address these challenges, the proposed IoT Urban Utilities Management System utilizes the ESP32 microcontroller to develop an intelligent and automated municipal management solution. The system integrates ultrasonic sensors to monitor manhole water levels and prevent overflow, while a GSM module sends real-time alerts to authorities. An RTC module enables scheduled control of water pumps and streetlights, ensuring efficient energy usage. The ESP32 processes sensor data and supports IoT connectivity for remote monitoring and data visualization, while an LCD and buzzer provide local alerts and system status updates. This smart system enhances operational efficiency, reduces resource wastage, improves public safety, and supports the development of sustainable and intelligent urban infrastructure management.
