REAL-TIME MONITORING OF WATER LEVELS USING ARDUINO-BASED ULTRASONIC SENSING SYSTEM: A LOW-COST APPROACH TO SUSTAINABLE WATER MANAGEMENT

Abstract

Water is an increasingly scarce resource, and efficient water management has become critical for sustainable development. This research presents the design and implementation of a low-cost, real-time water level monitoring system using Arduino Uno and ultrasonic sensor technology. The system measures tank water levels using non-contact ultrasonic sensors and provides real-time feedback through an LCD display, LEDs, and audible alerts via a buzzer. The project aims to reduce human intervention, prevent water wastage due to overflow or underflow, and support sustainable water resource management in residential, agricultural, and industrial applications. Results indicate high accuracy, low maintenance, and affordability, making the system suitable for large-scale adoption in water-scarce regions.
