Title	Title Tire Pressure Monitoring (TPM) System
Name	Name AN238
Date	Date 06/24/2015
Application Categories	Application Categories Automotive / Safety
Description	Description This document explains a typical tire pressure monitoring(TPM) system specifically intended for automotive use. It serves as a reference to design a real-world system based on various Microchip products. A TPM system primarily monitors the internal temperature and pressure of an automobile?s tire. There is a variety of system approaches to follow, although this one is a rather comprehensive auto-location system. An autolocation system can dynamically detect the position of a specific sensor, which is useful when tires are rotated. The heart of the TPM system is the Sensor/Transmitter (S/TX) device and it is based on Microchip?s rfPIC12F675.
