Etude d'un systéme de détection et de signalisation de présence d'un objet par un capteur pir

Abstract

This paper presents the method of detection and localization of moving objects in the field of view of PIR sensor .Passive infrared (PIR) sensors are sensitive to infrared (IR) radiation, and are mainly used for motion detection. In this thesis, we have exploited a mathematical model that allows us to better understand the analogical response of the PIR sensor. The proposed model highlights the relationship between the image formed on the detection elements, the distance of the object from the PIR sensor and the angle of displacement in the field of view of the PIR sensor, by a comparison between the simulation results and those obtained experimentally Translated with www.DeepL.com/Translator (free version)
