Light has an undeniable impact on the human body, as it can to some extent affect hormone secretion and emotional changes. Spectral power distribution (SPD) is the main indicator for evaluating the quality of light sources, but traditional spectral measurement equipment is bulky and expensive, and cannot be widely used in our daily life. In order to fill this gap, this article designs a low-cost and small lighting measurement device for measuring the circadian lighting, which obtains spectral data from 8 channels in the visible light range through multi-channel spectral sensors. Machine learni...
