Abstract
A system is provided for monitoring tire pressure which includes a sensor mounted within a tire that triggers a train of pulses when tire pressure reaches a level outside predetermined parameters. The system also includes a receiver mounted in operative proximity to the sensor at a location exterior to the tire. The receiver is electromagnetically coupled to the sensor and the sensor is activated in response to tire pressure reaching a level outside predetermined parameters. Also provided is an indicator which is coupled to the receiver, which signals when the tire pressure reaches a level outside predetermined parameters. The sensor is mounted within the tire that senses tire air pressure. The receiver is mounted within operative proximity to the sensor and at a location external to the tire and is electromagnetically coupled to the sensor to generate signals dispersed by the sensor that are indicative of tire air pressure sensed by the sensor. The tire pressure indicator is coupled to the receiver that converts tire air pressure signals generated by the receiver into a driver readable output.
