| Detailed Description | The infrared sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor). It utilizes the non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air, exhibiting excellent selectivity, no oxygen dependence, stable performance, and long lifespan; it also features built-in temperature compensation. This sensor is a compact, high-performance sensor manufactured by tightly integrating mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design. It is easy to use and can directly replace catalytic combustion elements, making it widely applicable in various situations involving flammable and explosive gases. |
| Main Applications | This infrared sensor can be widely used in HVAC and indoor air quality monitoring, industrial process and safety protection monitoring, and agricultural and livestock production process monitoring. |
