(54)	Sensor device provided with a circuit for detection of single or multiple events for generating corresponding interrupt signals

(57) Described herein is a sensor device (2) for an electronic apparatus (1), provided with: a sensing structure (5) generating a first detection signal (A_x); and a dedicated integrated circuit (6), connected to the sensing structure (5), detecting, as a function of the first detection signal (A_x), a first event associated to the electronic apparatus (1) and generating a first interrupt signal (INT1x) upon detection of the first event. The dedicated integrated circuit (6) detects the first event as a function of a temporal evolution of the first detection signal (A_x), and in particular as a function of values assumed by the first detection signal (A_x) within one or more successive time windows (T_s1-T_s3), and of a relation between these values.
