Tire pressure detecting device and tire monitor system

摘要

A tire pressure detecting device (30) fixed to a wheel (13) with a tire (15) includes a pressure sensor (40) detecting an internal pressure of the tire (15) and transmits data of detection by the pressure sensor (40) to a vehicle body (12) by radio. The tire pressure detecting device (30) further includes a compensation data storage (26) storing compensation data for detection error specific to the pressure sensor (40) and a compensation data transmitter (21S) obtaining the compensation data from the compensation data storage (26), transmitting the obtained compensation data to the vehicle body (12) by radio.
