Adafruit SCD30 NDIR CO2 Temperature and Humidity Sensor ...

The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration !


NDIR Principle | Cambustion

Knowledgebase. NDIR Principle. NonDispersive InfraRed (NDIR) detectors are the industry standard method of measuring the concentration of carbon oxides (CO CO2). Each constituent gas in a sample will absorb some infra red at a particular frequency. By shining an infrared beam through a sample cell (containing CO or CO2), and measuring the ...


Basic Principle of NDIR Gas Detection Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the BeerLambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).

Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive 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.
