Overview

The Color Sensor V3 uses the TCS34725 chip, which can simultaneously detect red, green, blue light, and ambient light (Clear light). It is equipped with an infared blocking filter to improve color detection accuracy. The built-in fill light supports low-light detection and features programmable analog gain and

integration time, allowing users to adjust sensing behavior accodording to application needs. It is suitable for advanced color detection and color temperature analysis applications.

Feature

• Four-channel sensing (RGB + Clear) with an integrated infrared (IR) blocking filter.

• Built-in automatic fill light with adjustable Analog Gain and Integration Time.

• Uses I²C communication interface, supports 3.3V ~ 5V voltage systems

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

• Recommended sensing distance is approximately 5-40 mm; sensing may become unstable or affected by ambient light if too far

Application

• Identification of sign or object colors

• Industrial or automated color recognition processes

• Light environment or color temperature variation sensing (suitable for smart lighting control)

Electrical Characteristics

Glossary of Terms:

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

2. Clear Channel* Represents the total intensity of unfiltered ambient light. The value range depends on sampling settings, with a maximum of 65,535. Under default settings in MATRIXblock, the typical range is approximately 0 to 2048. To adjust sampling time and gain, advanced settings via IDE programming are required.

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

4. I²C Specification Note** The specifications listed here are based on the TCS34725 chip. Actual implementation may vary slightly depending on module design.
