Pyroelectricity - Wikipedia

Very small changes in temperature can produce a pyroelectric potential. Passive infrared sensors are often designed around pyroelectric materials, as the heat of a human or animal from several feet away is enough to generate a voltage. [citation needed] Power generation. A pyroelectric can be repeatedly heated and cooled (analogously to a heat engine) to generate usable electrical power. One ...

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

2014-01-28· When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected.

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 ...
