Passive Infrared (PIR): Infrared Systems For Detecting ...

· The heart of passive infrared (PIR) sensor technology is the lens. As the “eyes” of the sensor, it collects the infrared energy data generated by matter in space. Moving energy sources, such as humans, will emit radiant heat that is then collected by the lens. These data are passed to the sensor circuitry for interpretation; based on this, a signal is transmitted to switch lighting in the ...

HC-SR501 (Passive Infrared) PIR Sensor | How it’s Works

· PIR Sensor full form is Passive infrared sensor, The “passive” word indicates this sensor does not produce any energy radiation or IR radiation for the detection of objects. This sensor mainly used for motion detection. It is can detect any objects which emit infrared radiation. But the most important thing it does not give information about the moving object. It means when a human passed ...

PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

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 ...

Design and Prediction of Detection Range for PIR(Passive ...

· In general, PIR(Passive Infrared) lenses are arranged in a x b array with a number of Fresnel lenses. PIR(Passive InfraRed) lenses are usually not flat and are mostly round or square. In addition, separate materials should be used that can be passed on to the FIR(Far Infrared). And if there are multiple Fresnel lens patterns in it, it’s hard to model and simulate accurately with an optical design program. FresnelFactoryKorea has developed PIR lenses …
