This is a low-cost open-source monitoring system to measure water transparency. Citizens build their own buoy with sensors and put it in the sea. It is possible to leave the KdUINO in the water for a long time. The buoy collects data on transparency, measured using the sensors on the KdUINO. It thus gives continuous transparency measurements in real time and provides coverage for a large coastal zone, something not possible using traditional radiometers due to their cost.
It is currently being upgraded to gather information on different colour bands (RGB). A do-it-yourself (DIY) version is being developed that will have better usability, as well as being lighter weight and more portable, under the MONOCLE framework.
