NDIR stands for Non Dispersive Infrared radiation and the carbon dioxide (CO2) sensors are based on NDIR technology. This technique is widely used to detect carbonbased gases such as CO2 that are present in the air. The CO2 gas enters the sensor and light from the Infrared (IF) source falls on CO2 molecules. These molecules absorb some amount of light at a wavelength of µm. This ...

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 ...

20210122· NDIR sensors also typically require a great amount of power to function, and they require frequent calibration which contributes to a higher total cost of ownership. And since NDIR is a proprietary technology, the sensors themselves can be quite expensive when purchased. The limitations of NDIR sensors are great, and any potential user should understand the pitfalls of using these sensors ...

Why NDIR? A nondispersive infrared (NDIR) sensor has a detector that measures how much infrared light of a specific wavelength is absorbed by the surrounding air. This measurement is then used to calculate the concentration of a specific gas. ›. Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy.

NDIR sensor is generally composed of the infrared source, optical cavity, dualchannel detector and an internal thermistor, as described by Figure 2. NDIR principle. Figure 2. NDIR principle Both channels are made of a thermopile, one is considered as a reference and the other one is considered as the active channel. Each channel has a specific wavelength filter. The active channel has a ...

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not prefiltered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using one of the following technologies: Thermopile ...

20211122· The NDIR sensor is a new and relatively simple gas sensors. In the sensor, the infrared radiation emitted by the light source passes through the measurement unit first, and there is a detection gas to be analyzed in the measurement unit.
