PROBLEM TO BE SOLVED: To provide a tire condition amount management system capable of securely receiving data from a specific sensor module whose data are wanted to obtain when a command signal requiring data transmission is transmitted from an outside module to the sensor module. SOLUTION: Each sensor module 3 has a self-identification code for distinguishing itself from other sensor modules. The command signal transmitted by the outside module 2 includes the self-identification code possessed by the sensor module 3 which is an object for obtaining the data. Each sensor module 3 is designed to transmit the data only when the self-identification code included in the command signal from the outside module 2 is identical to the self-identification code possessed by itself.
