nondispersive infrared sensor

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

NDIR Gas Sensors - Electrical Optical Components, Inc.

Nondispersive Infrared Gas Detectors. An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector.

On-Chip Non-Dispersive Infrared CO2 Sensor Based on an ...

In this paper, we propose a novel, miniaturized non-dispersive infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor has a simple structure, consisting of a hollow metallic cylindrical cavity along with access waveguides. A detailed analysis of the proposed sensor is presented. Simulation with 3D ray tracing shows that an integrating cylinder with 4 mm diameter gives an ...

Development of a novel non-dispersive infrared multi ...

01/06/2019· The infrared spectra of CH 4, CO 2 are required to design and develop a sensor, in order to know the infrared energy absorption (absorption bands). Fig. 2 shows the IR spectra of CH 4, CO 2 used to identify the absorption bands of each gas. Two absorption bands are observed for CO 2, the first one at nm and the second one at 14, nm, the first peak shows a higher absorption of ...
