The carbon dioxide gas sensor MH-Z1311A (hereafter 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, is non-oxygen dependent and has a long lifetime. It has a built-in temperature compensation, digital output, easy to use. The sensor is a high performance sensor manufactured by closely combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design.
