Oxybuoy: Constructing a real-time inexpensive hypoxia monitoring platform

Abstract

We present a low-cost sensor buoy designed for unattended dissolved oxygen measurement in aquatic environment. We describe the buoy's architectural design and three experiments that we carried out to demonstrate its viability: a laboratory test in a water tank with controlled oxygen level, a lake deployment and an extensive electric power consumption test. Our experiments indicate the viability of such an approach to dissolved oxygen monitoring and promise further advances in hypoxia studies. © 2010 ICST Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.
