Abstract
A code learning device of a tire monitor is used for motor vehicles having a tire monitor and a plurality of sensors, whereby each sensor is installed in individual tires of the motor vehicle, and each sensor module includes a radio signal transmitter for transmitting the conditions of the tires and the specific code of the sensor module via radio frequency signals. The code learning device includes an electric module having a processor, a memory, and a radio frequency signal receiver electrically coupled to the electric module for receiving the radio frequency signals, and dividing the radio frequency signals into a data signal and an amplitude signal. The data signal includes the conditions of the tires and the specific code of the sensor module such that the electric module can confirm the corresponding relation between the tires and the sensor module by way of the numeric value of the amplitude signal.
