TPMS is a warning device assembled on tires to measure tires’ pressure and temperature. It can transmit the values to the receiver in car. When the pressure and temperature inside the tire are abnormal, in order to ensure driver’s security, TPMS will have some warning signal to notify the driver to inspect the car's status.
