This paper introduces the conceptualization and implementation of a sea wave piezoelectric energy harvesting system designed for a self-powered IoT buoy sensor, tailored for the remote monitoring of water quality variables in fish farming. The developed autonomous system undertakes periodic measurements of temperature, pH, and dissolved oxygen, with the gathered data transmitted locally through a low-power wide-area network protocol to a gateway. The gateway is intricately connected to a cloud service, facilitating efficient data storage and visualization. At the heart of this innovation lies a novel buoy design capable of harnessing energy from sea surface waves. The proposed piezoelectric energy harvesting system comprises two pivotal components: an energy transfer mechanism responsible for capturing incident sea surface wave energy and a piezoelectric fin serving as the transducer. Extensive data analysis of sea wave patterns spanning nearly 25 years informs the design process. Subsequently, a prototype is meticulously crafted, fabricated, and rigorously tested in a controlled environment, showcasing promising results. The outcome is a self-powered remote monitoring tool poised to revolutionize fish farming scenarios by enabling seamless, automatic data acquisition, and storage.
