TCS3200 RGB Color Recognition Sensor Detector Module

This Arduino compatible TCS3200 color sensor module consist of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The main part of the module is the TCS3200 chip which is a Color Light-to-Frequency Converter. The white LEDs are used for providing proper lighting for the sensor to detect the object colour correctly. This chip can sense a wide variety of colours and it gives the output in the form of corresponding frequency.

Features:

• High-resolution conversion of light intensity to frequency
• Programmable colour and full-scale output frequency
• No need of ADC (Can be directly connected to the digital pins of the microcontroller)
• Power down feature
• Working temperature: -40°C to 85°C
• Size: 28.4×28.4mm (1.12×1.12″)

Applications:

• Colour sorting robots
• Test strip reading
• Colour matching tests

The TCS3200 chip consist of an 8 x 8 array of photodiodes. Each photodiode have either a red, green, or blue filter, or no filter. The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal circuits includes an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.
