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 ...

NDIR Sensor for Non-Dispersive Infrared Detection

This is a non-dispersive infrared (NDIR) approach. It has been shown (Jacquinot P. 1954 J. Opt. Soc. Amer. 44, 761-765) that optical filters are typically 1000 times more efficient than gratings and up to 100,000 times more efficient than prisms at separating IR wavelengths, so NDIR gas sensors offer real performance advantages over dispersive ...

Nondispersive Infrared Sensor - Assignment Point

NDIR is an industry term for “nondispersive infrared”, and is the most common type of sensor used to measure carbon dioxide or CO2. Infrared (IR) techniques are very popular in gas detection technology since many gases have characteristic vibration/rotation absorption spectra with narrow, non-overlapping bands in the infrared spectrum ...

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
