Overview | Adafruit SCD-30 - NDIR CO2 Temperature and ...

2021-01-06· 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 ...

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

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

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).

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

2017-07-11· The non-dispersive infrared (NDIR) carbon dioxide sensors rely on an infrared light source and detector to measure the number of CO 2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO 2 molecule counts. To combat sensor drift, during calibration a sensor is exposed to a known gas source, multiple ...
