Sensors – massive scale for oceans

Sensors have always been thought of as small tiny pieces of silicon that measures something flowing past its sensing surface. However, Draper Labs in Boston showed a waste plastic sensor on Oct 5th, 2018 at their laboratories in Cambridge, MA. These sensors allow the optical detection of soluble plastics in the ocean. The design is almost made to look like a spaceship but the interesting part about it is that it actively searches for the plastics. Instead of being a sensor loosely suspended in water, this will go out and actively search for plastics. It will search for plastics that are tiny and even micron sized.
The detection of plastic is a hard problem since the plastic is almost invisible in water but the detection is very important for recycling and cleaning our oceans.
