摘要： A transmitter of a tire condition monitoring apparatus has a pressure sensor, a transmitting circuit, and a transmission controller. The pressure sensor measures the air pressure of a tire. The transmitting circuit wirelessly transmits data indicating the measurement at a variable bit rate. The transmission controller controls the transmitting circuit). More specifically, the transmission controller varies the bit rate depending on the traveling speed of a vehicle, which is detected by a vehicle speed sensor. The transmission controller then causes the transmitting circuit to transmit data at the varied bit rate. Accordingly, regardless of the operation mode of the vehicle, the data is transmitted at an optimal bit rate.
