G4Plus IR 红外光谱的吸收特性进行浓度测量，无氧气依赖性和催化传感器的中毒现象，寿命长，准确红外气体传感器是基于 NDIR 原理设计的智能微型气体传感器，它利用气体对特定度高，性能稳定。该传感器具有模拟和数字两种信号输出接口，能直接输出经线性化处理和温度补偿的气体浓度值信号，更易于使用。

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.
