Pyroelectric Detectors - LASER COMPONENTS

A pyroelectric IR detector is a thermal detector in that it responds to the change in heat (IR) absorbed on its surface. Thermal detectors are polychromatic with a very wide spectral bandwidth. The nature of the pyroelectric effect is that in a highly-ordered crystal (or ceramic), a temperature change in the element causes its atoms to move slightly out of position. This rearranges its ...

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.

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

2014-01-28· To begin explaining how a basic sensor works, we'll use this rather nice diagram 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).

Noise in Pyroelectric IR Detectors

Noise in Pyroelectric IR Detectors App Note 13-02 The noise mechanisms discussed above are for the case where the impedance conversion is made with a JFET connected as a source follower. We now discuss the case where the impedance conversion is made with a current to voltage converter or transimpedance amplifier. Today there are quite a good number of opamps which have very low input …

Infrared detectors and arrays PYROSENS – for applications ...

Due to the physical principle of operation, pyroelectric infrared detectors can detect radiation in a very broad wavelength spectrum from about 100 nm (UV) to more than 1 mm (terahertz waves) without cooling. The series of PYROSENS single- and multi-channel detectors is optimized for the spectral range between μm and 30 μm. Depending on the type, the PYROSENS detectors are equipped with ...
