MH-411D carbon dioxide gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor). The sensor uses non-dispersive infrared (NDIR) principle to detect CO2 in the air. The sensor has no oxygen dependence, stable performance and long life.
Built-in temperature compensation.
The sensor is a compact high performance sensor made by combining mature infrared gas detection technology with micro machining and sophisticated circuit design.
