PROBLEM TO BE SOLVED: To provide a tire condition monitoring device which enables a user to easily grasp tire information by a portable communication terminal.SOLUTION: A tire sensor unit 3 comprises an NFC (Near Field Communication) tag 14. A portable communication terminal 4 comprises an NFC reader/writer 20 which performs short-range radio communication with the NFC tag 14. The portable communication terminal 4 can transmit a trigger signal to the NFC tag 14 of the tire sensor unit 3 via the NFC reader/writer 20. When the NFC tag 14 receives the trigger signal, the NFC tag 14 transmits a plurality of pieces of tire pressure data stored in a storage unit of the tire sensor unit 3 with the corresponding pieces of detection time to the NFC reader/writer 20. The portable communication terminal 4 displays the received pieces of tire pressure data with the detection time on a display unit 4a. |
