Abstract
A sensor includes an accelerometer, which, in operation, generates accelerometer data, and digital signal processing circuitry. The digital signal processing circuitry, in operation, generates, based on the generated accelerometer data, a value indicative of a cosine of an angle between an acceleration vector associated with current accelerometer data and a reference acceleration vector, compares the generated value indicative of the cosine of the angle between the vector associated with current accelerometer data and the reference acceleration vector with one or more thresholds and generates a tilt signal based on the comparison of the generated value indicative of the cosine of the angle between the vector associated with current accelerometer data and the reference acceleration vector with the one or more thresholds. The tilt signal may be used as an interrupt signal to an application processor.
