The Colour Sensor measures colour reflection coefficients of surfaces.  It has a built in halogen light source.  Each unit can be calibrated upon request. The colour reflection of a colored surface is shown as a graph or in numerical format. Measurement results can be saved as text or bitmap.  Spectral sensitivities are as follows:

Spectral range 420 .. 700 nm
Spectral response
Red - 420..530 nm
Green - 490-600 nm
Blue - 590-700 nm
Number of elements in the detector: 3
The Colour Sensor has 3 photo-detectors and distinct colour separation for RGB (red, green, blue).  Signal from each cell of the PDA is processed by a 10-bit analog-to-digital converter.  2 high-low opto-coupled outputs can be activated
