Ensure availability and sustainable management of water and sanitation for all is one of the Sustainable Development Goals settled by the United Nations for the 2030.?? However, today, billions of people in the world still live without safe drinking water and millions die every year due to waterborne diseases. People are dying due to contaminated and polluted water. For this reason, a new, real-time, effective, and low-cost device to detect various pollution could help improving the quality of life of a huge part of humanity, not to mention the reduction in deaths. Nowadays the water quality monitoring is performed without a real global "water quality standard": most water quality is evaluated at a local or national level.
