The water level sensor allows you to detect the height of water or some other liquid in the tank. This float sensor works on the principle of magnets and magnetic (reed) switches. Usually, it is mounted on the bottom or top of the tank, and when in water, the floating part with a magnet, triggers the magnetic switch. This alteration can be detected and trigger a certain action; eg filling the tank or launch alert.
