Abstract:
A pressure monitor for a vehicle tire comprising:a signal sending device, including a tire pressure sensor and a battery, for sending an electric signal in response to a tire pressure detected by said tire pressure sensor; and a signal receiving device for receiving the electric signal,wherein said signal sending device sends electric signals at predetermined sending intervals and sends an electric signal if a change in the value of the tire pressure in a predetermined unit of time is equal to or more than a predetermined standard value;wherein said signal receiving device further comprises at least one alarm for issuing an alarm on the basis of comparing the tire pressure detected by said tire pressure sensor with a predetermined alarm tire pressure, and said signal receiving device issues an alarm when the detected tire pressure is equal to or less than the predetermined alarm tire pressure; andwherein the standard value is determined on the basis of the predetermined sending interval and the predetermined alarm tire pressure.
