Pyroelectric Infrared is used in a wide range of industrial and commercial applications. They are a popular choice as they last longer, function better, and are incredibly accurate. Pyroelectric Infrared detectors are an infrared sensitive optoelectronic that detects infrared by applying the pyroelectric effect.
RS Components offer an extensive selection of high-quality Pyroelectric Infrared detectors from industry-leading brands Murata & KEMET.
Infrared is a type of electromagnetic wave that has a thermic effect and can be felt as thermal energy. When a temperature change occurs in proximity to the Pyroelectric Infrared sensor, the infrared rays enter the sensor and raise the surface temperature of Pyroelectric element. A surface charge is then generated and extracted as an electrical signal and provides an output. This allows Pyroelectric Infrared sensors to detect and absorb infrared energy that is naturally emitted by humans. Pyroelectric Infrared sensors possess some key features including
