A sensor (100) for detecting a rotational movement or an angular acceleration comprises at least one heating element (108) and at least one sensor element (110, 112) and a fluid surrounding the heating element (108) and the sensor element (110, 112), the heating element (108) producing in the fluid a convection flow zone through which an isothermal field is defined. The heating element (108) and the sensor element (110, 112) are arranged with respect to an axis of rotation of the rotational movement or of the angular acceleration to be detected, in such a way that the sensor element (110, 112) is displaced relative to the isothermal field when a rotational movement or an angular acceleration takes place.
