Molluscan Eye, the start-up that measures water quality using connected molluscs. Every day, an assessment of the quality of the aquatic environment is drawn up.
This report is provided in the form of colored emoticons and trend curves in order to perceive the state of water quality at a glance. The flaw is that it is an alert system and therefore no information on the nature or concentration of a pollutant for example. More than 90 valvometers have already been installed around the world.
