| Abstract: | A transmit module of tire pressure monitoring system is designed. The hardware and software are given. A silicon piezoresistive pressure sensor based on MEMS technology SP12 is applied to be a unit in the tire pressure monitoring. Single- chip microcomputer PIC16F628A is used to be the signal processing and transmission controlling unit. The TDK5110F which contains a fully integrated PLL synthesizer and a high efficiency power amplifier is a single chip transmitter. The module can monitor air pressure and temperature inside the tires and give off alarm properly, it helps a driver to avoid an accident. |
