Provided is a fluid pressure control device that includes an actuator and a body configured to house the actuator. The body has an opening arranged to receive pressurized fluid. The fluid pressure control device additionally includes a pressure sensor incorporated into the body relative to the opening to sense fluid pressure and to generate an electrical signal indicative of the sensed pressure. Furthermore, the fluid pressure control device includes an integrated circuit incorporated into the body, and operatively connected to the pressure sensor. The integrated circuit includes a transceiver configured to communicate with an external device by transmitting the electrical signal indicative of the sensed fluid pressure to the external device and receiving a control signal from the external device. The integrated circuit additionally includes a driver configured to power the actuator in response to the control signal.
