Disclosed herein is a tire pressure monitoring system (TPMS) device. The TPMS device includes: a pressure sensor recognizing an inner pressure of a tire; a pressure signal collecting processor collecting and processing a pressure signal of the pressure sensor; a motion sensor mounted in a vehicle body; and a motion signal collecting processor collecting and processing a motion signal from the motion sensor. Here, a position of the tire is determined by comparing a magnitude or a phase between the pressure signal and the motion signal.
