RGB Colour Detector

RGB Colour Sensor

• Sensor Chip: TCS3200 (RGB color detector)
• Detects static colour, the output is a square wave with frequency directly proportional to incident light intensity
• Supports fill-light using onboard LEDs

Specifications

• Power: 2.7V ~ 5.5V
• Ideal detection distance: 10mm
• Dimension: 36.0mm * 20.6mm
• Mounting holes size: 2.0mm

Applications

• Sorting by colour
• Ambient light sensing and calibration
• Test strip reading
• Color matching

How to Use the Sensor

To work with a microcontroller:

• VCC ↔ 2.7V ~ 5.5V
• GND ↔ power supply ground
• LED ↔ MCU.IO (controlling the 4 white LEDs)
• OUT ↔ MCU.IO (RGB colour output frequency)
• S0/S1 ↔ MCU.IO (Output frequency scaling selection inputs)
• S2/S3 ↔ MCU.IO (Photodiode type selection inputs)

S0/S1 selects the output frequency scaling factor, S2/S3 selects the colour filter as red, green, blue, then OUT outputs a square wave with frequency proportional to the selected colour intensity. The detected colour can be determined by the ratio of the intensity of red, green and blue.

Note:

• Avoid environment light noise
• White balance is required the first time the module is used, on module reset or on changing the light source
