Infrared Sensors Overview: Types, Functioning and Use ...

The sensor in the PIR motion detector consists of two halves because its purpose is not only to detect infrared waves but also to indicate a change as a signal for motion. The sensor is idle when there is no motion in the detection field. However, when a person or another living thing that radiates heat, such as an animal passes in the field range, it produces a positive differential change in ...

Overview | PIR Motion Sensor | Adafruit Learning System

2014-01-28· PIRs are basically made of a pyroelectric sensor (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor in a motion detector is actually split in two halves.
