Since our sensor series uses this effect they can be used at ambient temperature even in the presence of thermal noise.

First we define the terms like infrared radiation and pyroelectric infrared sensors (PIR).

Micro-Hybrid is able to offer all of their IR components, thermopiles, pyroelectric detectors and IR sources in this high temperature packaging. Applications to detect motion are many like: generating some. A pyroelectric detector is an infrared-sensitive element, which serve the detection of electromagnetic radiation - read more.

During further research, dual element types were developed with multi-facet mirrors or Fresnel lenses entering the field of motion detection, . In particular, PIR sensors could address the invasion of privacy issues raised by the use of camera-based surveillance systems.

Scientific interest in the properties of infrared radiation . Our productportfolio of thermopile arrays consists of linear arrays, 2D arrays, array modules and array application sets. We offer single, dual and quad sensor types and several types of linear arrays. These differences have an impact on the suitability of both technologies for different applications.

This highly reactive approach has low computational requirement, therefore it is well-suited to surveillance, industrial applications and smart environments. A polymer pyroelectric transducer represents an efficient solution in terms of spee sensitivity, and scale of integration, especially . It finds appli- cations in as diverse and wide areas as industrial production, auto- motive and aerospace applications , communications, health . The phenomenon of piezoelectricity, the release of electric charge under the application of mechanical stress, occurs in all noncentrosymmetric materials.
