TCS3200 chip is designed to detect the color of light incident on it. It
has an array of photodiode (a matrix of 8x8, so a total 64 sensors).
These photodiodes are covered with four type of filters. Sixteen sensor
have RED filter over them thus can measure only the component of red in
the incident light. Like wise other sixteen have GREEN filter and
sixteen have BLUE filter. As you should know that any visible colour can
be broken into three primary colours. So these three type of filtered
sensors helps measure the weightage of each of primary colours in
incident light. The rest 16 sensors have clear filter.
converts the intensity of incident radiation into frequency. The output
waveform is a 50% duty cycle square wave. You can use the timer of a MCU
to measure period of pulse and thus get the frequency.
The output of
TCS3200 is available in single line. So you would ask how we get the
intensity of RED,GREEN, BLUE and CLEAR channels Well it has two inputs
S2 and S3 that is used to select the sensor whose output need to be made
available on the out line.Specification
