Features

• Micro SD OTG Reader
• Micro USB Connector

What it is for

Illuminates data collected from sensors, such as temperature, on a micro SD card. Ideal for Arduino and ESP projects that require the storage of large amounts of data.

Tutorial: How to use GT-093 Micro SD OTG Reader micro usb

The GT-093 is a micro SD OTG reader that allows reading data from a micro SD card using an Android device or a computer. Ideal for anyone who wants to archive and access large amounts of data.

What you need

• Arduino Uno
• Micro SD Card
• Micro USB Cable
• SD.h Library

Steps

1. Connect the GT-093 to the VCC and GND pins of the Arduino.
2. Connect the DAT0 pin of the GT-093 to pin 10 of the Arduino.
3. Check the connection of the micro SD card to the GT-093.
4. Include the SD.h library in the Arduino code.
5. Configure the SD object with the connected pins.
6. Open the root folder of the micro SD card.
7. Read the data from the file.
8. Close the connection with the micro SD card.

Example code

#include <SD.h>

const int chipSelect = 10;

void setup() {
  Serial.begin(9600);
  if (!SD.begin(chipSelect)) {
    Serial.println("Card failed, or not present");
    return;
  }
  Serial.println("card initialized.");
}

void loop() {
  // leggi i dati dal file
}

Mini project

Create a data logger that stores the values read from a temperature sensor on a micro SD card.

Common mistakes

• Ensure that the DAT0 pin is correctly connected.
• Check the presence of the SD.h library.
• Check the physical connection of the micro SD card.
• Verify that the GT-093 is properly powered.

Recommended accessories

• Temperature sensor LM35
• 16GB micro SD card
• Micro USB cable
• Arduino Uno
