Open-source low-cost design of a buoy for remote water quality monitoring in fish farming.

Blog Article

In this paper we present the design of an open-source and low-cost buoy prototype for remote monitoring of water quality variables in fish farming.The designed battery-powered system periodically measures temperature, pH and dissolved oxygen, transmitting the information locally through a low-power wide-area network protocol to a gateway connected to a cloud service for Jewelry Holders data storage and visualization.We provide a novel buoy design that can be easily constructed with off-the-shelf materials, delivering a stable anchored float for the IoT device and the probes immersed in the water pond.The prototype was tested at an operating fish farm, showing promising results for a low-cost remote monitoring tool that enables Deflectors / Rain Guards / Visors automatic data acquisition and storage in fish farming scenarios.

All the elements of this design, including hardware and software designs, are freely available under permissive licenses as an open-source project.
