Description

technical field

[0001] The invention relates to a multi-channel infrared pyroelectric detector for gas and fire detection, in particular to a multi-channel infrared pyroelectric detector with scientific structure design, wide application, standard packaging, stable performance, high detection rate and high integration degree. Discharge detector. Background technique

[0002] At present, most of the domestically known infrared pyroelectric detectors are single-channel infrared pyroelectric detectors, which are mainly used in the fields of human body and anti-theft. Most of the known multi-channel infrared pyroelectric detectors in foreign countries are traditional linear structures, which do not have the function of mirror convergence and signal amplification, and have certain limitations in application field and accuracy.

[0003] The single-channel infrared pyroelectric detector does not have reference and compensation signals, and its accuracy has certain limitations. Th...
