The TCS230 is an 8-pin SOIC surface-mount package with 64 photodiodes integrated on a single chip. These diodes are divided into four types. Of these, 16 photodiodes have a red filter; 16 photodiodes have a green filter; 16 photodiodes have a blue filter; and the remaining 16 have no filters and can transmit all the light information.These photodiodes are cross-arranged within the chip, which can minimize the inhomogeneity of incident ray radiation, thereby increasing the degree of color recognition; On the other hand, 16 photodiodes of the same color are connected in parallel and evenly distributed in the diode array, which can eliminate the positional error of the color. When working, the required filter is dynamically selected through two programmable pins. The typical output frequency range of this sensor is from 2 Hz to 500 kHz, and the user can also select, 20% or 2% output scaling factor, or power off mode through two programmable pins.The output scaling factor allows the output of the sensor to adapt to different measurement ranges, improving its adaptability. For example, when using a low-speed frequency counter, a small calibration value can be selected to match the output frequency of the TCS230 to the counter.
