The TPMS Transmitter is installed to the valve stem in each tyre of a vehicle. The unit measures tyre pressure periodically and transmits this information by RF communication to a receiver inside the vehicle. In addition, the TPMS Transmitter performs the following functions: The main functions, which the TPMS transmitter must perform, are: Regularly measure the tyre pressure. Detect if motion is present. Use the combination of WAL and PAL protocols to determine which wheel the sensor is located in. This is based on RSSI received and ABS correlation data. Periodically transmit tyre pressures using RF at 433MHz and receive on one to two receivers depending on truck application using a specific RF protocol. Monitor battery condition and transmit to the system during the RF transmission. Sample pressure at a faster rate if a pressure delta occurs. The system must be notified of the pressure fluctuations. Chip Inductor and tuning components are used to poll the ASIC for the detection of a125KHz LF signal to place the sensor into specific testing modes.
