PURPOSE: A pneumatic pressure controlling system using a bluetooth RF(Remote Frequency) module is provided to enable to transmit and receive wireless data between a sensor and a solenoid valve unit that are a central controller and peripherals through the bluetooth RF module. CONSTITUTION: A pneumatic pressure controlling system using a bluetooth RF module is composed of a sensor(10), in which the bluetooth RF module is mounted, for detecting the displacement of an actuator; a central controller(20), wherein the bluetooth RF module is disposed, receiving a signal detected by the sensor through the bluetooth RF module, computing the signal in a CPU(Central Processing Unit), and outputting a control signal for operating a solenoid valve; and a solenoid valve unit(30), wherein the bluetooth RF module is installed, receiving the control signal output from the central controller through the bluetooth RF module, outputting a final solenoid valve control signal from the CPU according to the control signal from the central controller.
