Color sensor principle

TCS230 Use 8 Pin SOIC Surface-mount package , integrated on a single chip 64 Photodiode . These diodes are divided into four types.

Among 16 Photodiodes withRed filter;

16 Photodiodes with Green Filter;

16 Photodiodes withBlue filter;

Rest 16 Months without any filter , the light transmitted through the information may all .

The photodiode chip is arranged in a cross , it is possible to minimize unevenness of the incident radiation , thereby increasing the accuracy of color identification ;

the other hand , the same color 16 Photodiodes are connected in parallel , uniformly distributed in the diode array, the position error can be eliminated color.

When working through two programmable pins to dynamically select the desired filter. Typical output frequency range of the sensor from2 Hz ~ 500 KHz Users can also be selected by two programmable pins 100%,20%Or2%The output scale factor , or power-off mode. The output scale factor so that the output of the sensor can be adapted to different measurement ranges , improved its ability to adapt . For example , when using low frequency counters can select a small scaling value that TCS230 The output frequency and the counter matches .
