[0173] 3) The system continuously monitors water pressure to ensure that it does not exceed the water-saving threshold set by the user.

[0174] 4) The next morning, the system automatically returns to normal water pressure mode.

[0175] Example 4: Operation of water disinfection treatment unit:

[0176] 1) The micro-UV disinfection module is automatically activated when the water meter starts supplying water.

[0177] 2) The water flows through the disinfection unit, and the UV lamp emits UV-C light with a wavelength of 254nm to disinfect the water.

[0178] 3) The disinfected water is directed to the outlet, while the disinfection effect monitoring sensor detects the water quality.

[0179] 4) If the water quality is not up to standard, the system will increase the UV light intensity or extend the exposure time until the water quality meets the standard.
