PURPOSE: A tire pressure sensing system is provided to save the manufacturing cost by checking the position of the tire using the coil which is inside a sensor and a permanent magnet. CONSTITUTION: A tire pressure sensing system comprises a sensor unit(300), a magnetic force generation unit, a coil unit and a receiver(600). The sensor unit detects the pneumatic pressure and temperature of the tire and is installed on each tire. The magnetic force generation unit generates magnetic field and is installed in the car body corresponding to the sensor unit. The coil unit is included in the sensor unit in order to pass through the magnetic field with the rotation of the tire. The receiver detects the location of the tire by detecting the intensity and direction of current.
