The MH-410D infrared gas sensor is a general-purpose, intelligent, and miniature sensor. This infrared sensor utilizes the principle of non-dispersive infrared (NDIR) to detect CO₂ in the air, exhibiting excellent selectivity, no oxygen dependence, stable performance, and long lifespan. It also features built-in temperature compensation. This compact, high-performance infrared sensor is manufactured by tightly integrating mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design.
