Water pollution is a critical issue affecting aquatic ecosystems and communities relying on water bodies. By integrating STEM (Science, Technology, Engineering, Mathematics), an effective Water Body Monitoring System can be developed to monitor and manage pollution levels.

Science
Understanding water quality starts with identifying key parameters like:

pH Levels to measure acidity.
Turbidity to assess water clarity.
Temperature to monitor environmental changes.
Dissolved Oxygen to evaluate aquatic health.
These indicators reveal the state of pollution and its impact on ecosystems.

Technology
Sensors for measuring water parameters are connected to an IoT-enabled microcontroller like the ESP32. The device collects data and transmits it wirelessly to a cloud platform for analysis. This ensures real-time monitoring and easy access to information.

Engineering
A floating device is designed to house the sensors. It is made durable, waterproof, and solar-powered to ensure sustainability and long-term operation in harsh environments.

Mathematics
Collected data is analyzed using graphs and statistics to identify pollution trends. Alerts are generated when parameters exceed safe thresholds, enabling quick action.

The Result
This STEM-powered system provides real-time alerts, actionable insights, and a data-driven approach to reduce water pollution, showcasing how STEM disciplines can solve environmental challenges effectively.
