The Design of Tire Pressure Monitoring System Based on SP30

A tire pressure monitoring system is introduced and the basic frame and operating principle of the system are discussed in detail.The system consists of single-chip microcomputer,integrated sensor SP30 and RF transceiver module. The transmitting diagram,receiving and controlling circuits diagram,software flowchart and communication protocol are described.Applying integrated chip and low power consumption technology,the design has the characteristics such as small volume,light weight,low power consumption,high anti-jamming capability and long service of battery.The design provides reasonable and cheap resolving project for tire pressure monitoring system.
