A solenoid valve controlled by wireless communication, in which the operation of the valve is controlled by wireless communication, thereby reducing costs and labors necessary for installation and maintenance. The solenoid valve includes a valve body having an inlet port, through which fluid is introduced, and an outlet port, through which fluid is discharged; a plunger movably mounted inside the valve body to open or close one or both of the inlet and outlet ports; a solenoid, which drives the plunger to a position, in which the plunger opens or closes one or both of the inlet and outlet ports, when electric power is supplied; and a communication module provided on the valve body. The communication module receives a wireless control signal transmitted from outside and controls the electric power supplied to the solenoid valve depending on the wireless control signal.

1. A solenoid valve comprising: a valve body having an inlet port, through which fluid is introduced, and an outlet port, through which fluid is discharged;a plunger movably mounted inside the valve body to open or close one or both of the inlet and outlet ports;a solenoid, which drives the plunger to a position, in which the plunger opens or closes one or both of the inlet and outlet ports, when electric power is supplied; anda communication module provided on the valve body, wherein the communication module receives a wireless control signal transmitted from outside and controls the electric power supplied to the solenoid valve depending on the wireless control signal;wherein the communication module includes:a wireless receiver, which receives the wireless control signal;a controller, which outputs an operation signal for controlling an operation of the solenoid in response to the wireless control signal received by the wireless receiver;a power supply, which supplies a supply voltage to the wireless receiver and the controller; anda power controller, which controls a current supplied from the power supply or an external power source to the solenoid in response to the operation signal output from the controller;wherein the controller of the communication module compares the wireless control signal with a predetermined signal format and outputs, if the wireless control signal is equal to the predetermined signal format, the operation signal to the power controller;wherein the communication module further includes a status display that provides an optical or auditory indication of an error indication signal, which is output if the wireless control signal received in the controller is not equal to the predetermined signal format;wherein the controller of the communication module compares a valve specific identification code, included in the wireless control signal, with an identification code of the solenoid valve and outputs, if the identification codes are equal to each other, an operation signal to the power controller. 2. The solenoid valve according to claim 1, wherein the communication module has a frequency band of 2.5 GHz. 3. The solenoid valve according to claim 1, wherein the power supply comprises a battery. 4. The solenoid valve according to claim 1, wherein the communication module further includes a wireless transmitter that transmits an operating status signal indicative of the valve.
