A small device that is hung on the outside of the fish tank and two sensors come out of it and are placed in the water, the first sensor detects the temperature of the water and the second measures the degree of turbidity, the result appears on a screen on the body of the device so that the user can see the measurements.
I tried as much as possible to make the device smaller without affecting its functions.
More suitable for square fish tanks than round ones, because of the hanger.
