Color Sensor

• Sensor Chip: TCS3200 (RGB color detector)
• Detects static color, the output is a square wave with frequency directly proportional to incident light intensity
• Supports fill-light by 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 color
• Ambient light sensing and calibration
• Test strip reading
• Color matching

How to Use

In the case of working with a MCU:

• VCC ↔ 2.7V ~ 5.5V
• GND ↔ power supply ground
• LED ↔ MCU.IO (controlling the 4 white LEDs)
• OUT ↔ MCU.IO (RGB color 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 color filter of red, green, blue, then OUT outputs a square wave with frequency proportional to the selected color intensity. The detected color can be determined by the ratio of the intensity of red, green and blue.

Note:

• Avoids environment light noise

• White balance is required when the first time using the module, reseting the module, or changing the light source
