bluetooth 4.0 tpms system for car with 4 sensors which used by ABS.freescale chip.
intelligent Bluetooth tire pressure monitoring system:
To measure the tire pressure and temperature using pressure sensor installed on the tire, the Bluetooth 4 will pressure the temperature information from the system inside the tire is sent to the smart device, then the tire pressure data display. When the tire pressure, low pressure, high temperature, the system will alert the driver.
the advantages of intelligent Bluetooth tire pressure monitoring system:
Compared to the traditional 433 transmission Bluetooth monitoring system uses low-power Bluetooth 4, in the hardware, has a transmission distance, the advantages of lower data loss. In software, due to the popularity of Bluetooth 4 in smart devices, smart Bluetooth tire pressure monitoring system can be directly displayed on the smart phone, smart cloud mirror, central control system. In the display of diversity, the man-machine experience is better, and have online upgrade function
