Early infrared detectors are mainly used for scientific experiments and military testing. However, with the advent of low-cost detectors, their applications in industry and in civil applications have been expanding. This article describes the structure and performance of a low-cost ceramic thermoelectric infrared detector suitable for intrusion detection systems, infrared radiation measurement technology and other similar applications. First, the structure of the device Ceramic thermoelectric infrared detector is infrared sensor, low noise impedance matching circuit And infrared window composition. These components are housed in a TO-5 sealed enclosure
