Tyre pressure monitoring (TPM) microchip system

This document describes how a typical system of tire pressure monitoring (TPM), which specifically for the automotive industry. It is a reference to a system of real world based on a concept different from microchip products. Monitors a TPM system the internal temperature and pressure in the first place a car tyres. There are a variety of approaches to the system to follow. While East a fairly complete automatic positioning system.

A car tracking system can dynamically detect where a specific sensor, which is useful if the inflatable heart device threats.the TPM system sensor/transmitter (TX/S) and is based on microchip rfPIC12F675.


SYSTEM COMPONENTS
The TPM system includes the following key elements.
• Device sensor/transmitter
• RF Receiver module
Commander of low frequency (LF) device •
• Control unit
• Pressure (pneumatic)
