SEN0212 Gravity: TCS34725 RGB Color Sensor For Arduino

Introduction

The TCS34725 I2C arduino color sensor has a high sensitivity, wide dynamic range, and includes an IR blocking filter making it an ideal color sensing solution for use under varied lighting conditions. The TCS34725 color sensor also includes four ultra-bright LEDs to allow the sensor to work without external light resources. The module works via your Arduino’s I2C bus and includes PH2.0-4P and XH2.54 (breadboard) interfaces to meet a range of user scenarios.

Specification

Board Overview

SEN0212 Gravity: TCS34725 RGB Color Sensor For Arduino Board Overview
Num Label Description
1 SDA I2C-SDA
2 SCL I2C-SCL
3 VCC 3.3~5V
4 GND GND
5 LED Active-High/Vacant On
6 INT Active Low

Note:

  1. I2C address: 0x29
  2. XH2.54 interface (BreadBoard Compatible) need soldering.
  3. The paper of the blocking filter could be teared out.

Tutorial

In this tutorial, we'll detect the specimen RGB value, and simulate it with RGB LEDs

Requirements

Note: The sensor should be placed above the specimen, 3 ~ 10 mm
