Introduction

TCS3200 Color Sensor is a complete color detector, including a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The TCS3200 can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few. The TCS3200 has an array of photodetectors, each with either a red, green, or blue filter, or no filter clear . The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.

To TCS3002D, when choose a color filter, it can allow only one particular color to get through and prevent other color. For example, when choose the red filter, Only red incident light can get through, blue and green will be prevented. So we can get the red light intensity. Similarly ,when choose other filters we can get blue or green light.

TCS3002D has four photodiode types. Red , blue, green and clear, reducing the amplitude of the incident light uniformity greatly, so that to increase the accuracy and simplify the optical. When the light project to the TCS3002D we can choose the different type of photodiode by different combinations of S2 and S3. Look at the form as follows.

TCS3002D can output the frequency of different square wave occupies emptiescompared 50% ,different color and light intensity correspond with different frequency of square wave. There is a relationship between the output and light intensity. The range of the typical output frequency is 2HZ~500KHZ. We can get different scaling factor by different combinations of S0 and S1. Look at the form as follows.
