Overview | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· 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.

Nov 27, 2017· Infrared sensor values normally fluctuate in variant light conditions. When objects pass within the range, the light waves detect those objects and reflect the presence back to the sensor. Their wavelengths are less than that of microwaves. While they’re able to detect motion, they can also measure the emission of heat by an object.
