Abstract:

A Remote Online Monitoring System for Dams is proposed to ensure real-time monitoring and safety of dam structures. The system utilizes sensors such as an ultrasonic water level sensor, a pressure sensor (BMP280), and a piezoelectric vibration sensor to measure critical parameters like water levels, pressure, and structural vibrations. The collected data is processed by an ESP32 microcontroller, which acts as the central processing unit. This data is then transmitted to a cloud server for storage and analysis, enabling remote access and monitoring via a web or mobile dashboard.

The system also includes a 16×2 LCD for local data display and a solar-powered power supply unit to ensure continuous operation in remote areas. The absence of an additional gateway reduces complexity and cost, while the edge-computing capabilities of the ESP32 allow for efficient data handling. This monitoring system is compact, energy-efficient, and scalable, making it ideal for final-year engineering students to develop a robust and practical project that contributes to dam safety and disaster management.
