Pyroelectric Detectors | Sensors and Transducers

· Pyroelectric films are dielectric materials whose surfaces charge when radiated by infrared (IR). Plastics films have been used for this purpose, but the material that is favored for modern passive infrared (PIR) detection systems is lithium tantalite. The construction of a detector is as a capacitor with one metal plate and the other a pyroelectric…

What is Pyroelectric Infrared? (with picture)

Heather Phillips A passive infrared motion detector is a device that detects moving objects by detecting the infrared light they emit. Pryoelectric infrared is a passive infrared (PIR) technology that can sense a change in radiation emitted by living organisms and inanimate matter. It converts infrared light waves, which are below the light range that humans can see, to electricity via special ...

How to use Pyroelectric ("Passive") Infrared Sensors (PIR)

They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors. PIRs are basically made of a pyroelectric sensor (which you can see above 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 ...
