Monitoring Water Quality with a Spectrophotometer: a Proof of Concept of a Smart Buoy

Marine fisheries and aquaculture are fundamental resources in the livelihood and development of many countries. Real-time monitoring of the environmental conditions of marine aquaculture allows targeted interventions to maintain the health of fish species and the marine environment.This work describes the design and first low-cost prototyping of a proof-of-concept of a smart buoy to monitor the quality of water in IoT deployments. The buoy is connected to the Internet by a LoRaWAN link that transmits data acquired by a spectrophotometer that in principle allows us with a single sensor to obtain multiple parameters on water quality. Our solution is aimed at those countries that, despite basing their economies on aquaculture, do not have sophisticated and expensive technologies.
