The G4Plus IR infrared gas sensor is an intelligent miniature gas sensor designed based on the Non-Dispersive Infrared (NDIR) principle. It measures gas concentration by utilizing the absorption characteristics of gases at specific infrared wavelengths, with no reliance on oxygen and immunity to poisoning issues common in catalytic sensors. It boasts a long lifespan, high accuracy, and stable performance. The sensor features both analog and digital signal output interfaces, directly providing linearized and temperature-compensated gas concentration signals, making it even easier to use.
