How PIRs Work | PIR Motion Sensor | Adafruit Learning System

2014-01-28· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When ...

Pyroelectric detector | Sensor division knowledge

This so-called pyroelectric effect is used in sensor technology. For this, a thin pyroelectric crystal is coated perpendicular to the polar axis with electrodes. On the upper electrode of the crystal, an absorbing layer (black layer) is applied. When this layer interacts with infrared radiation, the pyroelectric layer heats up and surface charge arises. If the radiation is switched off, a ...

Pyroelectric infrared sensors (IR sensors) by InfraTec

The pyroelectric infrared sensors from InfraTec, also called pyroelectric detectors, can detect the electromagnetic radiation (UV, VIS, IR, THz) that hits them and measure their intensity. When the radiation hits, the pyroelectric crystal heats up and positive electrical charges occur. Without radiation, the crystal cools down and negative charges are generated. However, the charges are very ...

Pyroelectric Infrared Sensor PIR - Philadelphia University

The Pyroelectric Infrared sensor is made of a crystalline material that responds to the change of incident thermal radiation and develops a related electrical signal when a heat source (human body) crosses over the sensor FOV. This type of sensor responds to the variation of infrared radiation rather than the infrared radiation itself.
