本文介绍了新型中红外发光二极管 (LED) 和光电二极管 (PD) 光源/探测器组合的开发以及在非色散红外 (NDIR) 二氧化碳气体传感器中的使用。基于 LED/PD 的 NDIR 传感器具有快速稳定时间（传感器从冷启动、预热、获取并报告测量值以及再次断电所需的时间约 1 秒）、长寿命（>15 年）、低功耗和低成本。所述性能与“安装后忘记”无线部署传感器兼容，适用于建筑物、交通系统、园艺温室的室内空气质量监测/控制和节能以及安全、工业和医疗应用的便携式部署等应用。快速稳定时间、低固有功耗和循环操作可提供每次测量 mJ 的典型能耗，从而使用电池和/或能量收集策略提供扩展操作（约 2 分钟的测量间隔可使用一节 AA 电池提供超过 10 年的操作）。提供了与测量精度和噪声、温度性能、交叉灵敏度、测量范围（描述了两种光程变体，涵盖环境气体浓度至 100% 气体浓度）、与利用热源/热释电光源/探测器组合的 NDIR 的比较以及与能量收集的兼容性相关的具体性能数据。基于半导体的 LED/PD 加工与注塑反射光学器件和简单的组装一起提供了低成本大批量制造的途径。
This paper describes development of a novel mid-infrared light emitting diode (LED) and photodiode (PD) light source/detector combination and use within a non-dispersive infrared (NDIR) carbon dioxide gas sensor. The LED/PD based NDIR sensor provides fast stabilisation time (time required to turn on the sensor from cold, warm up, take and report a measurement, and power down again ≈1 second), longevity (>15 years), low power consumption and low cost. Described performance is compatible with “fit and forget” wireless deployed sensors in applications such as indoor air quality monitoring/control & energy conservation in buildings, transport systems, horticultural greenhouses and portable deployment for safety, industrial and medical applications. Fast stabilisation time, low intrinsic power consumption and cycled operation offer typical energy consumption per measurement of mJ's, providing extended operation using battery and/or energy harvesting strategies (measurement interval of ≈ 2 minutes provides >10 years operation from one AA battery). Specific performance data is provided in relation to measurement accuracy and noise, temperature performance, cross sensitivity, measurement range (two pathlength variants are described covering ambient through to 100% gas concentration), comparison with NDIR utilizing thermal source/pyroelectric light source/detector combination and compatibility with energy harvesting. Semiconductor based LED/PD processing together with injection moulded reflective optics and simple assembly provide a route to low cost high volume manufacturing.
