Harvesting Solar Power for IoT-Driven Water Purification and Monitoring Systems

An integrated, autonomous, and efficient water purification and monitoring system is presented, leveraging the Internet of Things (IoT) technology and solar energy for sustainability. The system features a solar-powered water decontamination scheme with filtration and sterilization methods, ensuring a clean water supply. Real-time monitoring and control are enabled through an IoT framework, optimizing system operation and operator intervention. The solar power supply unit utilizes a few photovoltaic (PV) boards to harness sunlight during sunny days and then store surplus electrical energy for persistent management of the whole purification and monitoring system. A microcontroller is the central hub, communicating with sensors to measure water quality parameters and oversee energy balance. Sensor data is transmitted to a Google Sheet for online storing and probing. A user-friendly interface that can be accessed via a mobile App or web dashboard, facilitates monitoring of water quality through different parameter values, system status, and energy levels. Alerts are generated for timely maintenance or adjustments, enhancing system reliability.
