Turbidity is the quantitative measure of suspended particles in a fluid. It can be soil in water or chocolate flakes in your favorite milk shake. While chocolate is something we soo want in our drinks, soil particles are totally undesired. Keeping aside the potable purposes, there are several industrial and household solutions that make use of water in some or other manner – for instance, a car uses water to clean the windshield, a power plant needs it to cool the reactors, washing machines and dish washers depend on water like fish. Now the question arises here: how do these machines get to know about the turbidity? We are blessed with nature’s evolutionary gift of senses to find out soil in the water, but what about your washing machines? No eyes to see, to tongue to taste, no skin to feel but just a plastic body with some buttons and motor inside. How does it so smart to work as per soil suspension???  Let’s find out in this Insight of a General Electric’s Turbidity Sensor. Interestingly, this sensor model has an additional feature to sense temperature changes. Let’s find that out too!!
