standard water level. If the water level exceeds the standard value, the processor
activates after a fixed time of 0.8 s. We verified the 20 mm value for the shape of
the bathtub used in this system. However, a bathtub with a smaller volume would
experience larger water level changes and surface ripples, necessitating the setting
of a higher threshold. If the fixed time threshold of 0.8 s is set shorter, the processor
makes incorrect judgments on large water surface ripples. On the other hand, if the
