SparkFun Spectral Sensor AS7265x
Advanced spectral sensor with 18 channels across UV, visible, and near-infrared spectrum. Perfect for spectroscopy and color analysis.
Say it to PAL
“Keep a log of the colors in the light.”
The code PAL writes
const data = await p.read('qwiic-as7265x', 'spectral');
p.log('Spectral: ' + JSON.stringify(data));When to pick it
18-channel spectrometer for scientific use — plant health (NDVI), material analysis, color science. Way more than most projects need.
Good to know
- Complex sensor with LED illumination control. Requires understanding of spectral analysis to interpret results.
- Gain and integration time need tuning for the specific application.
About it
The AS7265x is a sophisticated spectral triad sensor combining three chips to provide 18 individual spectral channels spanning 410nm to 940nm. Ideal for color matching, spectral analysis, agricultural monitoring, and scientific applications requiring detailed wavelength discrimination.
