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.

Wireless Low Cost CO2 Monitoring System Design and Evaluation Using Non ...

A NDIR sensor (Non Dispersive Infrared), as indicated by its name is a spec-troscopic type of sensor that uses infrared sources. It is mainly composed of an infrared lamp, an optical cavity and a dual channel detector. Light from the infrared source passes through the optical cavity where it inte-racts with the gas before affecting the active channel. This channel is fitted with a band-pass filter that allows …

Non‐dispersive Infrared Sensors - Carbon Dioxide Sensing - …

29/03/2019· Non‐dispersive infrared (NDIR) sensors use the concentration‐dependent absorption of electromagnetic radiation in the IR range. NDIR gas sensors use often a reference channel besides the measurement channel to compensate disturbing effects, for example by temperature or by ageing of the IR radiation source. Most common detectors in NDIR sensors are pyroelectric detectors and …

Non-Dispersive Infrared Sensing Technology | 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 systems and are the systems of choice.

Nondispersive Infrared Sensor - Assignment Point

Non-Dispersive Infra-Red (NDIR) detectors are the industry-standard method of measuring the concentration of carbon oxides (CO & CO 2). NDIR sensors are based on infrared spectroscopy, the principle that molecules absorb specific light frequencies that are characteristic of their structure. NDIR sensors for carbon dioxide are often encountered in heating, ventilation, and air conditioning …

Introduction to Gas Sensing Using Non-Dispersive Infrared (NDIR)

Non-dispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method. The main feature of this technique is that fixed narrow-band filters are utilized with separate IR detectors to detect a few gas absorption lines across a restricted wavelength range. This helps in eliminating the dispersive potion of a gas spectrometer. The simple design of the …
