Hello,
Using the sensors of AS7265x spectral triad, i have made i2c connections with ESP8266. But the values i’m getting is tooo raw data. i am currently unable to understand what the function ‘s.getCalibratedA();’ gives as its result. What do the values A till L and R till W actuallly mean?
Tarun.
Hi Tarun.
While I can’t explain how the code works to you, I can tell you that each letter represents a specific frequency of light. If you look in the [hookup guide, there’s a chart (also below) that tells what wavelength of light each letter represents.

For example, a higher reading for A, means you’re detecting more light at 410nm and a lower reading means you’re detecting less. By recording how much light the sensor is detecting at each wavelength, you can recognize an object by the light it’s reflecting. A pencil and banana are both yellow, but each will reflect different intensities of each wavelength of light so you could tell the difference between the two.](Spectral Triad (AS7265x) Hookup Guide - SparkFun Learn)
