Hall sensor and sensing method, and corresponding device

A Hall sensor comprising:

• a Hall sensing element configured to produce a Hall voltage indicative of a magnetic field when traversed by an electric current;
• a first pair of bias electrodes mutually opposed in a first direction across the Hall sensing element;
• a second pair of bias electrodes mutually opposed in a second direction across the Hall sensing element, the second direction being different first direction;
• a first pair of sensing electrodes mutually opposed in a third direction across the Hall sensing element, the third direction different than the first and second directions;
• and
• a second pair of sensing electrodes mutually opposed in a fourth direction across the Hall sensing element, the fourth direction being different than the first, second and third directions, each sensing electrode being between a bias electrode of the first pair and a bias electrode of the second pair.
