Color sensor principle

TCS230 adopts 8-pin SOIC surface-mount package, with 64 photodiodes integrated on a single chip. These diodes are divided into four types. Among them, 16 photodiodes have a red filter; 16 photodiodes have a green filter; 16 photodiodes have a blue filter; the remaining 16 have no filters and can transmit all light information. These photodiodes are arranged in a cross in the chip, which can minimize the unevenness of incident light radiation, thereby increasing the accuracy of color recognition; on the other hand, 16 photodiodes of the same color are connected in parallel and distributed evenly In the diode array, the position error of the color can be eliminated. When working, two programmable pins are used to dynamically select the required filter. The typical output frequency of the sensor ranges from 2 Hz to 500 kHz, and the user can also select 100%, 20% or 2% output scale factor, or power-off mode through two programmable pins. The output scale factor enables the output of the sensor to adapt to different measurement ranges and improves its adaptability. For example, when using a low-speed frequency counter, you can select a small scale value to match the output frequency of the TCS230 with the counter.
