1. SYSTEM OVERVIEW
Tire pressure monitoring system (called also TG for Tire Guard) is composed by:
- a tire guard wheel unit including an integrated pressure, temperature and acceleration sensor
and a RF transmitter.
- a RF receiver unit (not described in this document)
TG monitors the pressure of vehicle tire when driving or when it is stopped. An electronic unit
(wheel unit) mounted inside the tire periodically measures the current pressure. Thanks to a RF
link, this pressure information is transmitted to the RF receiver/decoder.
