the water level sensor is a device that measures the liquid level in a fixed container that is too high or too low. Suppose you are consulted by a company to design a capacitive type transducer for water level measurement in a baby swimming pool or a bath tub. Can you propose your design of required capacitive transducer with a neat block/schematic diagram and explain clearly how it works? Further, propose an input circuit, a signal conditioning and feedback loop/display device that it may requires and explain how each of them works in detail. If you think that there can be an alternate design for the required water level sensor with a different working principle, please propose the same with relevant details.
