A household tap water monitor includes a water meter, an electrical control valve, a single chip micyoco, an LCD, an electrical source circuit, a photoelectric detector connected to a first input port of the SCM, a reset switch connected to a second input port of the SCM and a keyboard connected to a third input port of the SCM. The water meter and the electrical control valve are connected in series between a tap water pipe and a main tap water inlet pipe. A control port of the electrical control valve is connected to a first output port of the SCM, and the LCD is connected to a second output port of the SCM. The photoelectric detector is used for monitoring the rotation of a small impeller in the water meter. The electrical source circuit is used to supply electricity for the components mentioned above.
