Rim

Tire

It is made of a PCB that supports the electronic hardware encapsulated inside a box
and polyurethane foam. It is self-powered by a battery and includes all systems for
measurements (pressure, temperature, centrifugal acceleration, and battery status),
RF emission and LF reception.

Theory of Operation
The sensor function is to provide to the receiver by RF frames the state of pressure
of the air in each one of the four tires of the car. The information given in the RF
frame indicates exactly the state of the car (rotating wheel or not) and the state of the
pressure in the tires.
At any time, the sensor must be able to detect some changes of the wheel behavior.
When the motion indicator is activated, the sensor enters the rotating mode. When
the motion indicator is deactivated, the sensor enters the interim mode for maximum
half an hour. During this period, the vehicle car return in rotating mode if it restarts
before the end of the 30 minutes stopped period or after 30 minutes time in interim
mode, the sensor goes automatically in stationary mode until it restarts and goes in
rotating mode.
