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.1 aCaayao, Lyka Jobelle M.eauthor.1 aDe Luna, Ralph Anthony O.eauthor.1 aMorandarte, Philip D.eauthor.  aAbanil, Ronereadviser.  aIsaac, Victor Solito DR.echair, panelist.  aBarbonio, Eugene P.epanelist.  aEbron, Jayson E.epanelist.  2ddcn0cUMhD278eiBSECEkUTHm2025  00102ddc4070aCSPCbCSPCcUTHd2025-10-13l0oUTH BSECE D278e 2025p006897UMr2025-10-13 10:01:06t1-1w2025-10-13yUM  c30705d30705
