Experimental Evaluation of Effect of Turbidity on the Performance of Visible Light Communication in an Underwater Environment

In tuna farming, turbidity measurement is highly important since one of the cause of death of tuna is a choking death due to muddy water. In this paper, we consider to use visible light communication modules for estimation of turbidity in underwater environments. If these modules can be used as turbidity meters, additional introduction of dedicated turbidity meters is not necessary. In this paper, through experimental evaluations using off-the-shelf visible light communication modules, we investigate the effect of turbidity on the performance of visible light communication in an underwater environment.
