Design of Tire Pressure Monitoring System Based on ZigBee

A new pressure measuring the system of automobile tire based on wireless sensor networks is introduced. It is composed by the ZigBee network equipment, ICS 87N absolute vacuum sensor and ATmega128L. etc. The problems existed in pressure measurement are successfully solved by putting the sensor into the tire, and with the temperature sensor and many other sensors a networks can be constituted by using wireless ZigBee networks. By Applying the high integrated IC and low power consumption technology, the system has the characteristics such as small volume, light weight, high anti-jamming capability and long service of battery. The design provides reasonable and cheap solution for tire pressure monitoring system.
