Arduino - PIR Sensor - Tutorialspoint

19/07/2018· What is a PIR (Passive Infrared) Sensor? A passive infrared sensor (PIR) is an electronic sensor which is used to detect motion. The sensor measures infrared (IR) light radiating from objects in its field of view. Mainly they have used in PIR based motion detectors. When a person in the field of the sensor moves, it detects a sudden change in infrared energy and the sensor is triggered (activated). …

Passive Infrared Sensor (PIR Sensor) -

PIR sensor is made of ceramic material that generates surface charge when exposed to infrared radiations. As the amount of radiation increases, the surface charge generated increases. A FET is used to buffer this signal. As the sensor is sensitive to a wide range of radiations, a filter is used which limits the infrared rays falling on the sensor to 8um-14um range. Thus the output of an IR sensor is a …
