1. A sensor for detecting acceleration, comprising:
- a plate having a support portion;
a mass connected by at least one hinge to the support portion;
at least one vibrating element having a first extremity connected to the support portion and a second extremity connected to said mass portion;
an excitation circuit which extends on the plate and is connected to the vibrating element; and
a temperature probe comprising a conductive track which is of a resistance that varies as a function of ambient temperature and which has a portion fixed on at least the hinge and the mass.
