Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

How does an NDIR CO2 Sensor Work? |

Modern NDIR CO2 sensors. Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined ...

Signal conditioning for NDIR sensor - Application note

NDIR sensor. Bandwidth. The pulsed light of the IR source of the NDIR sensor works generally at a very low frequency (few Hz). It is important to limit the bandwidth of the application as much as possible in order to limit the noise. A first order low pass filter is realized thanks to the RC network. with a -3 dB cut-off frequency ...

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors ...

CO2 IR Wavelength. A basic NDIR sensor consists of an infrared light source, a sample chamber, an infrared filter, and infrared detector. For carbon dioxide sensing, room or duct air is allowed to flow in and out of the sample chamber. Infrared light waves are created by the source and sent through the sample chamber to the detector. As the infrared light passes through the air in the chamber ...

Nichtdispersiver Infrarotsensor – Wikipedia

Ein nichtdispersiver Infrarotsensor oder NDIR-Sensor ist ein spektroskopisches Gerät, das überwiegend als Gassensor eingesetzt wird. Besonders geeignet sind NDIR-Analysatoren zur Bestimmung der Konzentration von Kohlenstoffmonoxid, Kohlenstoffdioxid oder Kohlenwasserstoffen in einem Gas. Ein typisches Anwendungsgebiet ist die Analyse der Abgase von Verbrennungsmotoren.

How Do CO2 Sensors Work?

NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice. For CO2, the most commonly used wavelength is µm. This wavelength is not absorbed at all ...
