Colour Sensor

Add a colour sensor to your project for colour sorting, matching, colour strip reading or ambient light sensing!

Features

• 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 by onboard LEDs

Specifications

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

How to Use

Product Wiki: https://www.waveshare.com/wiki/Color_Sensor

In the case of working with an MCU:

• 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 of red, green, blue, then OUT outputs a square wave with a 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

• Sensor only - no cable included
• Avoid environment light noise
• White balance is required when the first time using the module, resetting the module or changing the light source
