In view of low cost ZigBee, low power, small range, low complexity personal area network features, so the design of the technology for the vehicle with tire pressure monitoring system. Ensure the standard tire pressure is the vehicle in the daily maintenance and driving to prevent the key tire, and the tire pressure monitoring system (TPMS) emerge as the times require. This design is the use of the perfect support for the latest version of the ZigBee technology of the second generation of system on chip CC2530 chip to realize the tire pressure monitoring alarm function. This paper mainly introduces the application and Realization of the design of tire pressure monitoring system, using pressure sensor wireless nodes in ZigBee wireless network, to realize the automatic collection and transmission of the tire temperature and pressure data. Because of the use of ZigBee technology, greatly reduce the system cost and power consumption, to ensure the long service life system. After testing, tire pressure monitoring system can real time automatic monitoring of temperature and pressure on the tire, through ZigBee wireless mode to transmit the information
