Cat No: INGS-LJX-0004 Datasheet
Product Name: Infrared CO2 Gas Sensor, 0 to full scale
Quantities: - +
| Detailed Description | The 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. |
| 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. |
