Jul 25, 2021· 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 its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

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 Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).

Aug 04, 2021· I am trying to use (NDIR CO2 sensor Mikroelectronika) with Arduino Mega 2560 utilizing the Click shield. Mikroelectronika provides libraries for their platform (likely proprietary), hence i have no idea how to manage to do this with arduino. Here is the code I tried from the library page.
Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm-700nm).
