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 ...

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

higher levels of CO˚. Non-Dispersive Infrared (NDIR) technology is the most common method of measuring CO˚ in Indoor Air Quality analyses. The NDIR sensor consists of the following (see image below): 1) Infrared (IR) Lamp, 2) Gas Sample Chamber, 3) Wavelength Filter, and 4) an IR Detector. Carbon Dioxide (CO˚) is a colorless, odorless gas that is produced naturally in the environment, and ...

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

The existing CO2sensors can be categorized into 2 types: electrochemical sensors and non-dispersive infrared (NDIR) sensors. Electrochemical sensors measure the CO2concentration by measuring a change in the electrical properties of materials induced by the CO2adsorption. They have the advantage of being low cost and compact [11–14].
