H2O Sense: a WSN-based monitoring system for fish tanks

Abstract

In oceans, fish usually live in an environment that is best suited for their growth. When these fish are introduced into man-made environment, e.g. in mariculture and aquaculture set-ups, the physical parameters might stray from their ideal values, resulting in improper growth and undesired outcomes. Hence, to prevent these undesirable outcomes, continuous monitoring of the physical parameters of the water such as pH, temperature and dissolved oxygen is required. In this work, we present a system called H2O sense, which continuously monitors the physical parameters of the water in tanks and alerts the user in case the values deviate from ideal. We use only low-power, low-cost hardware and open-source development tools, which makes the system easily applicable to various settings. The deployment of our system in the Maritime Laboratory of the University of Namibia shows its efficacy. Furthermore, we evaluate in detail the performance of our system and discuss its applicability in similar challenged environments.

“…Its hyperspectral camera, for example, presents sensing applications such as H 2 O sensing for monitoring the parameters in the fish tank and signals to the farmer. 65 Also, a variety of sensors such as wireless sensor networks enable the accurate isolation of actual data from noise. In contrast, others use an electrochemical cell to offer yield signals by which the existence of an analyte can be determined.…”
