Improvements to NDIR-based carbon dioxide sensors have made it the most common solution for measuring CO2 concentrations with better accuracy across extremely wide ranges up to 100% volume. How NDIR 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 …
Carbon dioxide meters use NDIR, an infrared absorption technology that detects CO2 molecules. These molecules absorb radiation, which changes the light transmission intensity between an infrared source and detector. This change is analyzed by a photodetector which then outputs a voltage signal proportional to the CO2 concentration. Infrared absorption is the most efficient way to detect carbon ...

NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs. Infrared light absorption of a particular frequency or ...

The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means it's a lot bigger and more expensive, but it is the real thing ...
Carbon Dioxide CO2 Sensor. 1 PPM Resolution, Highly Responsive. Prana Air Carbon Dioxide Air Quality sensor type is NDIR (Non Dispersive Infrared Radiation). The resolution ranges between 0-10,000ppm. The sensor is capable to detect change of 1ppm. The sensor is compact and cost effective with high response and accuracy.
Based on SmartIR technology, the sensor consumes only in full-speed operation, delivering two carbon dioxide measurements per second. That’s typically 50 times lower powered than standard NDIR sensors. Other benefits of the SmartIR technology are also included – robustness and vibration proof, being based on sold state LED technology.
A nondispersive infrared sensor (or NDIR sensor) ... NDIR sensors for carbon dioxide are often encountered in heating, ventilation, and air conditioning (HVAC) units. Configurations with multiple filters, either on individual sensors or on a rotating wheel, allow simultaneous measurement at several chosen wavelengths. Fourier transform infrared spectroscopy (FTIR), a more complex technology ...
