Tips: Working Principle of NDIR CO2 Gas Sensor?

This type of CO2 sensor module is an intelligent general-purpose, small sensor that detects CO2 in the air using the principle of non-dispersive infrared (NDIR). Good selectivity, no oxygen dependence, long life. Built-in temperature compensation; digital output and analog voltage output at the same time, easy to use. Carbon dioxide sensor is a high-performance product that closely combines mature infrared absorption gas detection technology with precise optical path design and precise circuit design. The sensor can be used to monitor production processes in smart homes, agricultural greenhouses and animal husbandry.
