<p>The present invention provides a small-sized pressure measuring module suitable for replacement of a tire, and a tire pressure monitoring system. The pressure measuring module detects pressure of air within a tire included in a wheel assembly attached to a vehicle body, and wirelessly transmits data on the detected pressure and a module ID of the pressure measuring module to a pressure monitoring device mounted on the vehicle body. The pressure measuring module has an antenna and an identification code. At least a portion of the antenna protrudes to the outside of the wheel assembly from the surface of a wheel included in the wheel assembly through a through-hole communicating with an inner space of the tire. The antenna wirelessly transmits the detected pressure value and the module ID to the pressure monitoring device. The identifier can be viewed from the outside of the wheel assembly and indicates the module ID.</p> |
