Abstract
A transponder and sensor apparatus with on-board power supply is mounted in or on a vehicle tire. A pressure sensor, a temperature sensor and a tire rotation sensor are mounted in a housing along with the transponder, the power supply and an antenna. Upon receiving an interrogation signal from a remote interrogator, the transponder activates the sensors to sense tire pressure and temperature and then backscatter-modulates the radio frequency signal from the interrogator with the tire condition parameter data from the sensors to return the backscatter modulated signal to the interrogator.
