1. Autonomous device which is intended to be carried by a tire and wheel assembly in order to detect revolutions of said assembly, comprising at least one sensor producing signals, which is intended to be integral in rotation with said assembly such that revolutions of said assembly correspond to revolutions of said sensor, characterized in that the sensor is a passive sensor, the produced signals of which are proportional to the temporal variations of a magnetic flux.
