H2O Web Cloud: A Smart IoT-Based System for Wastewater or PureWater Monitoring and Visualization

This research presents a low-cost IoT-based smart wastewater monitoring system that utilizes turbidity and water flow sensors to measure water quality in real-time. The system is built using Arduino and transmits data over WiFi to a dynamic web dashboard designed with PHP, MySQL, and Chart.js for effective visualization. The H₂O Web Cloud interface displays purity levels and wastewater trends for each day, enabling households and municipal bodies to track pollution and take early action. The goal of this project is to promote sustainable environmental practices through accessible and scalable technology. This project was developed by second-year undergraduate students from Dr. D.Y. Patil Technical Campus, Pune under the guidance of Prof. Nitin Mali.
