Abstract
A weight sensor comprises a sensing system including a target piece and a sensing element, configured to provide changes of a magnetic field, being generated by motion of the target piece. The sensing element senses these changes and provides a signal representative of the position of the target piece. An integrated circuit with processing means can process signals from the sensing element. The flexible piece receives a force stimulus, so that upon exerting a force on the flexible piece by a product due to the weight of said product, the displacement of the target piece with respect to sensing elements can be sensed.
