When an external module transmits an instruction signal requesting for a data transmission, to a sensor module, a tire state quantity managing system can surely receive data from a particular sensor module to be acquired. Each of the sensor modules (3) has an identifier to distinguish itself from other sensors. The instruction signal transmitted from the external module (2) contains the identifier held by the sensor module (3) from which data is to be acquired. The sensor module (3) transmits data only when the identifier contained in the instruction signal from the module (2) coincides with the identifier held by the sensor module (3). |
