Abstract
PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection. PIR sensor outputs a voltage corresponding to the temperature change of the sensor element. PIR sensor has two detector elements connected in series with opposite polarities. This arrangement prevents triggering to an event caused by the change of background IR. PIR sensor was modelled and simulated using the Ray Optics Module and AC/DC Module with its electric circuit interface. The model includes the optics and the pulse shaping electric circuitry.Description
