A PIR sensor or passive infrared sensor is an electronic sensor that is used to measure infrared light that is radiating from objects that are in its scope of view. This kind of technology is often used in PIR-based motion detectors.
All objects that have a temperature above absolute zero are emitting heat energy in radiation form. Since radiation is not visible to the naked eye an only radiates infrared wavelengths, it can be detected by electronic devices.
The term passive refers to the fact that these PIR devices do not radiate energy. The device works by detecting infrared radiation that is reflected or emitted by objects. The way it works is that infrared radiation enters the front of the sensor which is called the sensor face.
At the center of the PIR device is a solid-state sensor which is made from pyroelectric materials. These materials generate energy when they are exposed to heat. The typical size of the sensors is approximately 1/4 inch square.
Other materials that are commonly used in PIR devices include caesium nitrate, gallium nitride, polyvinyl fluorides, cobalt phthalocyanine, and derivatives of phenazopyridine. The sensors in these devices are often made as part of an integrated circuit.
