Overview
NT-B2422C carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose, small-scale sensor that uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has good selectivity, no oxygen dependence, and long life. , Built-in temperature compensation, digital output, easy to use. The sensor is a high-performance sensor made by closely combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design.
