Color Sensor Module
The color sensor module comprises an illuminant, digital
color sensor and the mechanical block. The Avago
white LED (HSMW-C191) is used as the illuminant/light
source and digital color sensor (ADJD-S311-CR999) as
the detector. The mechanical block which is made with
delrin, will not only acts as the casing but also features
an alignment gauge for maintaining an optimum gap
between sensor and the targeted surface. The recom-
mended distance of the sensor from the surface is 2.5 to
4mm for reflective sensing.
The ADJD-S311-CR999 is a cost effective, CMOS digital
output RGB+C color sensor in miniature surface-mount
package with a mere size of 2.2x2.2x0.76mm. The color
sensor’s basic architecture comprises integrated RGB+C
filters built on a uniformly distributed photodiode array,
a logic control core, and a gain selector with an ADC
that supports digital communication. The uniform RGB
filters and photodiode array minimize the effect of light-
gradients caused by optical misalignment and irregular-
ity of surfaces.

Wavelength (nm)
The output allows direct interface to micro-controller or
other logic control for further signal processing without
the need of any additional components. With its wide
sensing range, the sensor can be used for many appli-
cations with different light levels, simply by adjusting
the gain setting. Sensitivity control is performed by the
serial interface and can be optimized individually for
the different color channel. The integrated ADC helps to
remove unwanted noise caused by analog signal pre-
conditioning. Additional features include a selectable
sleep mode to minimize current consumption when the
sensor is not in use. For more details of ADJD-S311-CR999
