In this paper, the anti-flat tire design process is divided into two parts: the tire module and the host module. The micro-controller MC68HC908RF2 is the core of the tire module. The integrated sensor MPXY8020A executes tire pressure and temperature measuring. The transmitter integrated inside the micro-controller executes wireless transmittal task. MC33594 executes wireless receive task in the host...
In this paper, we utilize the contactless power transmission technique in RFID system to achieve the battery-less tire pressure monitoring system (TPMS). The system adopts a high-efficiency class-E power amplifier to transmit RF power. The circuit for the whole power transmission circuit from the tire transponder to the reader is modeled so as to achieve the optimal circuit parameters for a high efficiency...
