CO2 Sensor Measurement Range, Accuracy and Precision ...

NDIR CO2 sensors take a new reading anywhere from 20 times a second to once every 30 seconds. As each reading is taken the sensor's on-board software takes into account all the previous measurements and report the average. This solves the problem of precision. If you want a more precise CO2 reading, look for a sensor with a higher frequency of ...

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 ...

Non-Dispersive Infrared (NDIR) Carbon Dioxide Sensors ...

Jun 09, 2021· NDIR CO2 Sensor. Non-dispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas.

NDIR Sensor for Non-Dispersive ... - Edinburgh Sensors

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 - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

AQ Sensors vs Instruments - 2B TecHnologies

While NDIR instruments make use of CO2 gas sealed in one half of a rotating filter wheel to rapidly block and pass wavelengths absorbed by CO2, NDIR sensors, developed originally for HVAC systems where high accuracy is not required, make use of a narrow bandpass filter to limit the wavelength range detected. A second reference detector with a ...
