Objective: To develop and demonstrate a solar-powered, real-time water quality monitoring prototype for lakes and rivers using IoT-based sensor networks.

India faces severe challenges in maintaining the quality of its lakes and rivers, impacting millions dependent on them for drinking water, agriculture, and livelihood. Manual water testing is infrequent, labor-intensive, and often delayed, resulting in unchecked pollution and health hazards for communities and ecosystems.

This project proposes an automated, solar-powered water quality monitoring system deploying real-time sensors for parameters such as pH, turbidity, dissolved oxygen, temperature, and electrical conductivity. The system uses IoT-enabled data transmission to a cloud dashboard, powered sustainably by solar panels suitable for remote or off-grid locations.

Key features include: a floating or bank-mounted prototype with industrial-grade water sensors, a microcontroller (e.g., Arduino/ESP32), solar charging circuit, real-time wireless data upload (GSM/LoRa), alert generation for threshold breaches, and a user dashboard. The working model will be demonstrated in a campus water body or test tank, showing live data acquisition, visualization, and alert functionality.

This solution supports municipal authorities, environmental regulators, and local communities by enabling continuous water quality surveillance, rapid response to pollution events, and scalable deployment across urban and rural India.
