Abstract :

This paper proposes a method to implement Tyre Pressure Monitoring System (TPMS) in vehicles. TPMS measures the air pressure inside pneumatic tyre of automobiles. The proposed TPMS has an electronic unit that directly screws onto the stem of tyre. The unit includes a pressure sensor and switch, signal conditioning unit, microcontroller, RF (radio frequency) transmitter and battery. An on–board RF receiver communicates with the TPMS unit and displays real–time tire pressure of all tyres.The unit can be easily detached and re–attached to the tire. Modification to the tire is not required. The system and each TPMS unit have unique to prevent false data reception from neighboring vehicles. Tyre replacement or maintenance will not affect the system�s working. Warning is generated whenever tire pressure crosses the maximum or minimum safe pressure level, or when it changes auptly. This lower level and upper limit of tyre pressure or safe range of aupt change can be modified by user through the user interface. The system can be implemented on any vehicle. It has given accurate results while proving to be user friendly
