Monitoring of water quality is an important element of environmental protection, aquaculture, and public health, as it facilitates the detection of pollution, ecosystem health assessment, and sustainable water resource management. Conventional methods of monitoring use manual sampling and laboratory analysis, which are labor-intensive, costly, and cannot provide real-time monitoring. To tackle these challenges, this work introduces a smart floating buoy system that continuously, real-time assesses the water quality through automated sensor integration and renewable energy sources. The system consists of advanced sensors to detect the major water quality parameters of temperature, humidity, pH, and turbidity. These parameters play a crucial role in monitoring aquatic environments, identifying sources of pollution, and ensuring optimal conditions for aquaculture and ecological equilibrium. The system is powered by the sun, enabling prolonged stand-alone use with minimal need for maintenance and the absence of constant power input. This cost-efficient strategy ensures sustained deployment on far-flung and inaccessible water bodies, thereby positioning the system as appropriate for widespread environmental monitoring. The gathered data is presented on an LCD screen in real time for users to instantly see water quality fluctuations. Moreover, the system is made to be affordable, expandable, and modular to allow easy modifications for other applications of water monitoring, such as industrial wastewater testing, lake and river condition evaluation, and aquaculture control. The outcomes of this research provide an impetus for the creation of next-generation environmental monitoring platforms, which have future possibilities in the fields of climate change science, pollution management, and sustainable water policies.
