2023年2月24日 · Pyroelectric infrared detectors (PIRDs) have a number of advantages over other IR sensors, including room-temperature operation, wide wavelength sensitivity, and low cost, leading to their use in many applications and a market expected to reach U.S.$68 million by 2025.

Excelitas Pyroelectric Infrared Detectors define the leading edge of motion detection technology, offering a variety of both digital and analog Pyroelectric IR Detectors to serve a wide range of applications in smart home, smart city, IOT, burglary detection and security systems.

Pyroelectric detectors make mid-range infrared affordable. You use what is already there — 100% natural and harmless. You can use the invisible glow of objects and people to detect, count, monitor, locate, activate, conserve, protect, or warn. It is passive technol-ogy. Visible light goes from 0.4 to 0.7 micrometers on the wavelength spectrum.

Pyroelectric detectors are sensors for light which are based on the pyroelectric effect. They are widely used for detecting laser pulses (rather than continuous-wave light), often in the infrared spectral region, and with the potential for a very broad spectral response.

The essential characteristics of pyroelectric detectors are the responsivity SV, the noise equivalent power NEP and the specific detectivity D*. They are defined in the steady-state condition for sinusoidal processes. They generally depend on modulation frequency f, wavelength λ and detector temperature T.
