Self-powered sensing module and system for monitoring the conditions of the tyres of a vehicle provided with at least one self-powered sensing module

A description is given of a self-powered sensing module (10) comprising at least one sensor (Sp, St, Sa) suitable for detecting an operating parameter of a vehicle tyre, transmission means (Tx) of the at least one signal detected by the at least one sensor (Sp, St, Sa) and supply means (30, 40, 50) for the at least one sensor (Sp, St, Sa) and the transmission means (Tx), the supply means (30, 40, 50) comprising a piezoelectric generator (40) electrically connected to a harvesting device (50) of the piezoelectric energy, which are mounted at the tyre inflation valve (15), thereby being easily replaceable and making optimum use of the mechanical vibrations of the vehicle. A description is also given of a system for monitoring the conditions of the tyres of a motor vehicle including at least one self-powered sensing module made in this way.
