Abstract

To support SDG 14, this study presents a buoy-based water quality monitoring system designed for cage aquaculture in Penghu, Taiwan. The system floats on the sea, enabling continuous water quality monitoring with real-time location tagging. It consists of three main components: an offshore buoy, an on-site client, and a remote server. The offshore client, controlled by an NI myRIO, integrates various water quality sensors and a GPS module to accurately measure pH, oxidation-reduction potential, dissolved oxygen, total dissolved solids, and conductivity. GPS data is transmitted to the remote server for real-time location display.The server, programmed with LabVIEW, handles data processing and provides a user interface, facilitating real-time data transfer to server via TCP/IP. A solar power system and relay module on the buoy conserve energy by disabling power when measurements or data transmission are unnecessary. Tested in a sea area near Magong, Penghu, this system demonstrated reliable performance, issuing alerts when water quality exceeded preset thresholds. This approach reduces labor costs and supports the effective realization of SDG 14.
