Solar-Powered IoT Floating Buoy for Continuous Multi-Parameter Water Quality Monitoring

The solar-powered floating buoy was successfully developed to monitor water quality in real time using pH, temperature, turbidity, and TDS sensors. During testing, the system displayed a pH value of 4.14, temperature of 0°C, turbidity of 100, and TDS of 20. The application successfully displayed sensor readings and provided control options for the floating buoy. However, the temperature reading of 0°C may indicate a sensor connection or calibration issue, and the other readings require verification using standard instruments. Runtime was measured at 2.5 hours with the motors running and 4 hours with the Wi-Fi module and display active, but sensor error was not measured during this test. Overall, the project demonstrates the potential of solar-powered technology for continuous water quality monitoring, with further calibration and testing needed to improve accuracy and reliability.
