Abstract: The invention relates to a sensor arrangement that comprises a luminosity sensor that allows using luminosity measurements in a room. In an aspect of the invention, the luminosity sensor allows determining a level of sun radiations that allows correcting temperature measurements, in order to obtain an effective temperature of the room. In other aspects of the invention, luminosity measurements are processed by a processing logic that combines them with meteorological predictions to calculate parameters related to the impact of solar radiations on the temperature of the room, such as the orientation of the room, or the position of the sensor in the room.

Abstract: In a number of aspects, the invention discloses a device (100) comprising one or more infrared light sources (40, 41); one or more visible light sources (50, 51); an image sensor (10); a processing unit (20) configured to analyze a series of images of a region of interest output by the image sensor; a control unit (30) configured to generate one or more of an activation of the one or more visible light sources or an alarm based on a command received from the processing unit; wherein the analyze comprises detecting a moving foreground in the series of images of the region of interest, tracking one or more characterizing features in the moving foreground and classifying the one or more characterizing features into two of more types of objects of interest, a type of an object of interest determining a command sent by the processing unit to the control unit.
