TCS230 TCS230 8-pin SOIC surface mount package, on a single chip, you have 64 photodiodes. These diodes are divided into four types. 16 of the red filter photodiode; 16 photodiodes with a green filter; 16 photodiodes with a blue filter; the remaining 16 without any filter can pass optical information. Compact Design Since the photodiode chip is in several stages, it is possible that it minimizes the non-uniformity of the incident radiation, thus increasing the accuracy of color recognition; on the other hand, the same color of the photodiode 16 is connected in parallel, evenly distributed in the diode array, you can eliminate the color of position error. Description For example, when using a low-speed frequency counter, you can choose a small scaling value to which the output frequency of the TCS230 and the counter correspond. Easy operation Use two programmable pins to dynamically select the desired filter. Typical output frequency range of the sensor from 2 Hz to 500 kHz, users can
