OPERATION OVERVIEW
The Base Station wakes up the Sensor modules in each tire through the Low
Frequency Initiator to poll the pressure, temperature data and checks the battery level
in a sequential manner. The Base Station communicates to the LF initiator via the LIN
network. The LF initiator transmits a wake up challenge via a 125 kHz ASK modulated
signal to the Tire sensor module after a command has been received from the Base
Station. The 3-axis Analog Front End (MCP2030) of the Tire Sensor module validates
the incoming challenge and wakes up the microcontroller from sleep only if the pream-
bles match. The Tire Sensor module will then measure the pressure and the tempera-
ture, check the battery level and transmits the data to the Base Station via a 433.9 MHz
signal. The Base Station will display the information on the LCD after receiving the data.
The Base Station module contains a PIC18F4680. It is also implemented with a
MCP201 LIN Transceiver and MCP2551 CAN Transceiver for communications via LIN
or CAN.
The LF Initiator module contains a PIC18F2680. The module also contains a MCP201
and MCP2551 for LIN or CAN communication.
The Tire Sensor module contains a PIC16F684 with a MCP2030, a three-axis Analog
Front-End (AFE). The analog pressure sensor used is the MS5407-AM from Intersema.
