A smart water supply valve system according to an embodiment of the present invention comprises an inflow unit for being supplied with water through one or more pipes; a valve for allowing/suspending the flow of water input through the inflow unit; a first sensing unit for sensing the pressure or flow rate of water unit input through the input unit; a second sensing unit for sensing at least one of the movement, the shape, and the heat distribution of an object; a controller for controlling the amount of opening/closing of the valve or the flow rate of water on the basis of sensing outputs from the first and second sensing units; and an outflow unit for discharging water supplied from the pipe.
