CO2 This carbon dioxide gas sensor is a general intelligent infrared gas sensor (hereinafter referred to as the sensor). It uses the principle of non-dispersive infrared (NDIR) to detect the CO2 in the air. It has no oxygen dependence, stable performance, long service life, and built-in temperature compensation. The sensor is a compact high-performance sensor made by combining infrared absorption gas detection technology with micro-machine processing and excellent circuit design.
