Overview

The MATRIX Color Sensor (Color Sensor V2) is an RGB sensing module that supports I²C communication. It features a built-in fill light, color classification functionality, and multi-format output capabilities. It can return sensing data in RGB, CMYK, grayscale formats, and includes automatic light source adjustments and gamma correction. It can reliably detect and classify a variety of common colors, making it suitable for applications such a symbol recognition, object classification, and automation control.

Feature

• Supports 3.3V to 5V operating voltage

• Supports RGB, CMYK, and Grayscale output formats

• Built-in 14-color auto classification (Color Number) function

• Supports gamma correction, closely mimicking human vision

• Automatic or PWM dimmable fill light to adapt to different lighting conditions

• Uses I²C communication interface, supports 100~400kHz transmission rate

• RGB value range is 0-255, representing the intensity of each channel

• Recommended sensing distance is approximately 5-10 mm; sensing may become unstable or affected by ambient light if too far

Application

• Identification of signs or route colors

• Industrial or robotic automatic classification systems

• Grayscale monitoring and light intensity evaluation

• Color sensing and logic judgement training in educational experiments

Electrical Characteristics (Module’s Electronic Component Characteristics)

Glossary of Terms:

1. Red / Green / Blue Channel Wavelength* Indicates the main wavelength positions of red, green, and blue light received by the sensor, measured in nanometers (nm).

2. I²C Transmission Speed* Indicates the data transfer rate, measured in kilohertz (kHz). A higher value means faster communication.

3. I²C Input Low Voltage (VIL)* If the voltage sent by the controller is below this value, the sensor will recognize it as 0 (LOW).

4. I²C Input High Voltage (VIH)* If the voltage sent by the controller is above this value, the sensor will recognize it as 1 (HIGH).
