Yocto-Spectral-C

The Yocto-Spectral-C is a device that measures light intensity across 13 spectral channels of visible light between 380 nm and 900 nm and applies a predictive model to interpret the measurements and estimate the corresponding color in several color spaces, including RGB, HSL, XYZ, and OkLab.

The device can measure the color of emissive sources such as screens or LEDs, but also inert surfaces, which can be illuminated using white LEDs included on the module, chosen to emit light similar to the light spectrum of the sun.

The Yocto-Spectral-C allows instant color measurements via USB, but also records spectral measurements on an integrated flash memory and allows them to be read back later via USB.

The circuit has been designed to allow the spectral sensor to be offset by a few meters, simply by cutting the circuit board in two pieces and soldering a small 4-wire cable to the connection points provided.
