Includes bibliographical references. This study presents a low-cost, real-time water quality monitoring system for Lake Buhi, a freshwater resource vital to the local economy and ecology. The system employs an Arduino Nano and ESP32 microcontroller to measure temperature, pH, turbidity, and dissolved oxygen (DO) using calibrated sensors. Sensor data is transmitted via Wi-Fi to a cloud server and displayed in a web-based graphical user interface (GUI). Results show 0% error in temperature, pH, and turbidity sensors, and a 0.87% average error for DO, proving the system's accuracy. The device addresses the need for sustainable environmental monitoring, offering a reliable alternative to manual sampling in aquaculture zones. Caayao, Lyka Jobelle M. author.
