The unit (1) has an inclinometer (5) e.g. microelectromechanical systems type dual-axis accelerometer, measuring variation of absolute angle with respect to vertical of a reference surface of a case (2), a part of the case or a support e.g. electronic board (3'), of internal functional elements (3). The elements are housed in the case fixed to a wall, mast or roof by a fixation accessory (4) e.g. articulated arm. The inclinometer delivers a measured signal exploitable by the unit or a security, alarm and/or monitoring system. A sensing element is in the form of a micro-system made of silicon. |
