Abstract
Abstract Transmitters of a tire condition monitoring apparatus that monitors condition of vehicle tires. Each transmitter has a measuring sensor, a transmission circuit, a vehicle speed sensor and a controller. The measuring sensor measures condition of the corresponding tire. The transmission circuit periodically transmits data representing the tire condition. The vehicle speed sensor detects moving of the vehicle. The controller sets a delay time, the delay time being a period from when the vehicle speed sensor detects moving of the vehicle to when the data representing the condition of the corresponding tire is transmitted. The delay time varies from one transmitter to another.
