SYSTEM AND METHOD FOR PROVIDING INFORMATION ABOUT PRESENCE IN A SPACE

The invention relates to a system (100) for providing information about presence in a space (101), the system comprising:- a movement sensor (10) for generating a first signal upon detecting movement;- a presence sensor (20) for generating a second signal upon detecting presence, being a temperature-based matrix sensor (20) comprising an array of sensing elements;the system comprises:- processing and/or control means (30) in communication with the movement and the presence sensors, configured to generate a presence signal upon receiving the first signal and/or the second signal; and configured to obtain background information of the presence detection field (21), the background information comprising reference temperature values of the array of sensing elements of the presence sensor (20) and being obtained:- upon the movement sensor (10) not detecting movement; and/or,- upon the presence sensor (20) detecting presence, and for each sensing element with presence, using the measured temperature value of some surrounding sensing elements not having human presence, or, if all surrounding sensing elements have human presence, using the measured temperature value of some sensing elements surrounding the former surrounding sensing elements not having human presence.
