1. A tire pressure monitoring sensor moveable inside a tire or a tire inner tube, comprising:

  • a rotatable housing having a curved outer surface portion, the housing configured to hold components of a tire pressure monitoring sensor, the components including;

    a pressure sensing/transmitting unit comprising;

    a pressure sensing portion for sensing an interior pressure of a tire and outputting a signal indicating the interior tire pressure;

    a processor portion electrically coupled to the pressure sensing portion for processing the output signal indicating interior tire pressure received from the pressure sensing portion to generate a monitoring signal indicating the current interior pressure of the tire;

    a transmitter portion coupled to the processor portion for creating a transmission signal including tire pressure information for transmission outside the tire;

    an antenna electrically coupled to the pressure sensing/transmitting unit;

    at least one battery electrically coupled to the pressure sensing/transmitting unit for providing electrical power to the pressure sensing/transmitting unit;

    wherein the components of the tire pressure monitoring sensor are assembled within the housing such that during rotation of a tire or tire inner tube inside which the housing and components are positioned, the movement of the housing and components is reduced within the tire when the tire is rotating.
