Abstract
A transmitter of a tire inflation monitor performs wireless transmission of data concerning tire inflation pressure from an antenna coil to a receiver. The transmitter includes a signal generation circuit, which is connected to the antenna coil. The signal generation circuit generates a trigger signal for activating or inactivating a controller of the transmitter based on a particular control signal received from a predetermined external controller through the antenna coil. When the controller is activated by the trigger signal, the transmitter starts wireless transmission of the data. When the controller is deactivated by the trigger signal, the transmitter is in a sleep state. In this way, data transmission from the transmitter is easily and externally started or stopped.
