4CO2-5000 NDIR MODULE
Datasheet download
Product Description

This infrared sensor functions based on the NDIR principle for monitoring carbon dioxide (CO2) presence. It features a highly accurate optical system equipped with a durable light source and a temperature-compensated infrared detector with dual channels. The electronic circuit includes a microprocessor with embedded intelligent software, which handles signal acquisition, processing, and output. Furthermore, it simultaneously performs environmental temperature compensation, rectifies response non-linearity, and offers multiple output options.
