The heating sensor PIR detector by radiation and its computer simulation

Abstract

In the security industry is the most commonly used PIR detector. At its behaviour is focused in this work. It was necessary to design a mathematical model of heat sensor simulation and thermal behaviour of the sensor in COMSOL Multiphysics environment followed by verification of the proposed mathematical model. Theoretical and mathematical conclusions became the basis for the subsequent implementation of workplace IR radiation for measuring the properties of radiation sources and sensors, in particular spatial characteristics PIR detectors. © 2015, North Atlantic University Union.
