Example Code for Arduino-I2C Data Reading

Hardware Preparation

• DFRduino UNO Controller x1
• SEN0611 Gravity: Color Temperature Illuminance Sensor x1

Software Preparation

• Arduino IDE Click to Download Arduino IDE
• Download and install DFRobot_ColorTemperature library. How to Install Library?

Wiring Diagram

Other Preparation Work

• Connect the module to the UNO controller according to the above wiring diagram, of course, you can also use the expansion board, which can be more convenient and faster to complete the project prototype.
• Switch the selector switch on the sensor to the I2C side.
• Download and install DFRobot_ColorTemperature library. How to Install Library?
• Note: Power off when switching the switch

Sample Code

#include "DFRobot_ColorTemperature.h"
DFRobot_ColorTemperature CT(&Wire);

void setup()
{
  Serial.begin(115200);
  while(CT.begin() != 0){
    Serial.println(" Sensor initialize failed!!");
    delay(1000);
  }
  Serial.println(" Sensor  initialize success!!");
}

void loop()
{
  Serial.println("-------------------------------");
  Serial.print("LUX: ");
  Serial.println(CT.readLUX());
  Serial.print("CCT: ");
  Serial.println(CT.readCCT());
  Serial.print("X: ");
  Serial.println(CT.readX());
  Serial.print("Y: ");
  Serial.println(CT.readY());
  Serial.println("-------------------------------");
  delay(500);
}

Result

Open the serial monitor of Arduino IDE, adjust the baud rate to 115200, and observe the serial print result to obtain the final color temperature, illuminance, and X, Y color coordinates data.

Additional Information

• Ensure the sensor is connected correctly and the I2C mode is selected.
• Power off before switching the communication mode switch.
