Abstract: A method for detecting and monitoring events on a territory, including the use of a directional sensor movable about a vertical axis of an angle between 0° and 360° and movable about an horizontal axis between 0° and 90°, includes the steps: A. dividing the first rotation in a first number of first angular sectors and the second rotation in a second number of second angular sectors so as to divide the territory into ring sectors; B. scanning the territory to individuate alterations of predefined chemical-physical parameters with respect to reference values; C. between the time intervals of step B, scanning the ring sectors wherein the alterations have been individuated; the territory being so cyclically scanned by step-bystep directing the directional sensor towards one or more of the ring sectors, detection of an event occurring by comparison of detected values with reference values for one or more chemical-physical parameters.

Abstract: The invention relates to a method for detecting and monitoring events on a pre-determined territory, comprising the use of at least a directional sensor (1, 1?, 1?) and at least a relevant device for moving said at least directional sensor (1, 1?, 1?) with a first canonical rotation about a vertical axis (2) of an angle between 0° and 360° and a second canonical rotation of an angle (?) between 0° and 90° about an horizontal axis perpendicular to the laying direction of said at least one directional sensor (1, 1?, 1?), the method comprising the step: A. dividing said first rotation in a first number of first angular sectors and said second rotation in a second number of second angular sectors so as to divide the territory into ring sectors (RS); the method being characterised in that it further comprises the following steps: B.
