Abstract
A tire condition monitoring apparatus includes transmitters. Each transmitter is installed in a vehicle tire and is powered by a battery. Each transmitter includes a sensor for detecting a condition of the associated tire, a transmission circuit for wirelessly transmitting data representing the condition and a controller that controls the sensor and the transmission circuit. The controller controls each sensor to detect the condition at predetermined detection intervals. Also, the controller controls the transmission circuit to transmit data that represents the detected condition only when the detected current tire condition has changed from the previously transmitted tire condition by a predetermined value .alpha.1 or more. As a result, significant changes of the tire condition are immediately communicated to a driver, and battery strength is conserved.
