1. A system of detecting tire information, the system comprising:

  • a measured value transmitter that includes a first resonator with a pressure sensor and a second resonator without the pressure sensor, which are mounted in a tire of a vehicle; and

    a controller that is provided in the body of the vehicle that transmits a signal used for resonance of the first and second resonators to the measured value transmitter, and receives from the measured value transmitter a signal associated with the resonant frequency of the first resonator and a signal associated with the resonant frequency of the second resonator, so as to calculate a measured value on the basis of the resonant frequencies of the first and second resonators,wherein characteristics of a piezoelectric single-crystal oscillator included in the first resonator are made closely analogous to those of a piezoelectric single-crystal oscillator included in the second resonator.
