The present invention provides an attitude sensing device and an attitude sensing method, and in particular techniques for determining an attitude in three-dimensional space of a reference axis of a package with which the attitude sensing device is associated. The attitude sensing device comprises an electromechanical sensor having a rotatable shaft operable to rotate about its axis to any shaft angle and a mass coupled to the shaft. The mass causes the shaft to rotate as the mass adopts a gravity-induced position. The electromechanical sensor is operable to provide an electrical signal in dependence on the shaft angle. The attitude of the reference axis being derivable from the electrical signal. By this approach, a simple arrangement is provided by which the attitude of the reference axis may easily be determined over the required operating range.
