Findicator, which means finger+indicator, is a whole new concept focusing on the problem of detergent remaining after cleaning the bowls and dishes.
Nowadays almost everyone uses detergent for cleaning dishes, but the dish-cleaner itself is hard to wash out. And the surface active agent in the detergent is harmful to human body.
This device can detect the amount of remaining detergent and give signal when the dishes get rid of the harmful chemicals. It is based on the fact that the surface active agent can change the conductivity when it is added into water. The smart device can make life safer and easier, also saves a lot of water.
