The Spectral 2 Click Board™ is a multispectral colour sensing device, which uses the state-of-the-art sensor IC for very accurate colour sensing. The sensor on the Spectral 2 Click Board™ provides multi-spectral sensing in the visible range of wavelengths from approximately 430nm to 670nm with the full width at half maximum (FWHM) of 40nm.
The Spectral 2 Click Board™ provides a direct reading of the six different colour components with the 16-bit precision, as well as the calibrated reading, that gives 32-bit float values with an 8-bit biased exponent and a 23bit fraction part, processed through the Spectral ID engine. The sensor also integrates two programmable LED channels with constant current drivers, useful for indication and for providing the backlight for the measured colour object.
