Microduino-ColorDetector

Microduino-Color detector is a color detection senor.

This module adopts TCS3414CS color chip and it can be connected through IIC interface. Based on 8×2 filtered photodiode and 16-bit analog-digital converter, you can measure light or light reflection on the surface of an object to acquire color value.

Features

• High accuracy and sensitivity;
• Low-consumption, long product life and high-stability;
• Small and easy to install.

Specification

• Electrical specification
  • Operation voltage: 3.3 ~6.0 V
  • Input device
• Tech parameters
  • ROHS authentication: YES
  • Operation temperature: -40 ~ 85 °C
• Size
  • Size of the sensor: 5mm*5mm
  • Size of the board: 20mm*20mm
  • 1.27mm-ptich 4Pin interface
• Connection method
  • Interface: IIC
  • Pin description: GND, VCC, signal 1 and signal 2. Since the output signal is IIC, you need IIC interface to receive signals, which can connect Sensorhub's IIC pin.

Development

Preparation

• Make sure you build Microduino IDE or refer to: Microduino Getting started
• Core selection
  • 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core.
  • 2. Adopt Microduino-Core or Microduino-Core+ as the core plus Microduino-USBTTL as the program download module.

Program

[MicroduinoColorSensor]

• Define variable values; RGB reading range.

  #define redMax 32767
  #define greenMax 32767
  #define blueMax 32767
  int redValue,greenValue,blueValue;

• readRGB(); Read RGB color function

• Reflect RGB value (0~32767) to (0.225);

 redValue=map(red, 0, redMax, 0, 255);
 greenValue=map(green, 0, greenMax, 0, 255);
 blueValue=map(blue, 0, blueMax, 0, 255);

Hardware Buildup

• Connect the sensor to the IIC interface of the Sensorhub with a wire.

Microduino-Sensorhub

mCookie-Hub

• Connect the core, Sensorhub and the Color Detector to a computer with a USB cable.
• Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started

• Download the program above.
• Select the right port from Tools→Serial Port in Arduino IDE and then download program.
• Open the serial monitor after download. The console will print current RGB value circularly.

Application

Microduino-Color detector is suitable for environment color detection.
