Solar Based Water Purifier

– This project presents a solar-powered water purification system designed to deliver safe and affordable water using renewable energy. The system utilizes solar energy to power water filtration and includes sensors that continuously monitor key water quality parameters such as turbidity and total dissolved solids. A microcontroller processes this data and displays real-time values on an LCD screen while simultaneously uploading the readings to a cloud-based platform for remote monitoring. To make the system user-friendly and self-sustaining, a coin-operated module is integrated, which activates a water dispensing pump upon valid payment. The purified water is then delivered for a fixed duration, ensuring regulated access and reducing water waste. This innovative solution addresses environmental sustainability, energy efficiency, and ease of deployment, making it suitable for off-grid communities, public installations, and disaster-struck areas. The proposed system promotes decentralized water purification and supports broader efforts toward universal clean water access.
