Example Code for Arduino UNO-All Sensor Data

Hardware Preparation

• DFRduino UNO R3 + Gravity IO Expansion Shield x 1
• SCI DAQ Module x1
• SEN0334 Gravity: SHT31-F Digital Temperature and Humidity Sensor x1
• SEN0228 Gravity: I2C VEML7700 Ambient Light Sensor x1
• Double-head PH2.0-4P Connector x2
• Gravity 4P Connector x1

Software Preparation

• Arduino IDE
• Download and install the .zip library DFRobot_RP2040_SCI Library. (About how to install the library?)
• Or search and install the DFRobot_RP2040_SCI library in the library manager

Wiring Diagram

Other Preparation Work

• Ensure the SCI DAQ module is properly connected to the Arduino UNO via the Gravity IO Expansion Shield.
• Install the required library in Arduino IDE.

Sample Code

#include "DFRobot_RP2040_SCI.h"

DFRobot_RP2040_SCI_IIC sci(/*addr=*/RP2040_SCI_ADDR_0X21, &Wire);

void setup() {
  Serial.begin(115200);
  while(!Serial){                                                     //Waiting for USB Serial COM port to open.
  }

  Serial.print("Initialization SCI DAQ Module...");
  while(sci.begin() != 0){
      Serial.println("failed. Please check whether the hardware connection is wrong.");
      delay(1000);
      Serial.print("Initialization SCI DAQ Module...");
  }
  Serial.println("done.");
}

void loop() {
  String ifAll = sci.getInformation(sci.eALL, true);
  Serial.println(ifAll);
  Serial.println();
  delay(1000);
}

Result

Additional Information

• The output format is "Name 1: Value 1 Unit 1, Name 2: Value 2 Unit 2".
