Weather-resistant and shock-proof designUsage Examples### Example 1: Raspberry Pi Data LoggingIn this example, we'll use the SanDisk 32GB Micro SD-SDHC Memory Card to store sensor data on a Raspberry Pi single-board computer.Hardware RequirementsRaspberry Pi (any model)
SanDisk 32GB Micro SD-SDHC Memory Card
Breadboard and jumper wires
Sensors (e.g., temperature, humidity, pressure)Software RequirementsRaspbian OS (latest version)
Python 3.xCode Example (Python)
```python
import os
import datetime
import time# Set up the SD card as the root filesystem
os.system("sudo mount /dev/mmcblk0p1 /mnt")# Create a directory for data logging
os.makedirs("/mnt/data", exist_ok=True)while True:
# Read sensor data (e.g., temperature, humidity, pressure)
sensor_data = read_sensor_data()# Create a timestamped file for data logging
file_name = f"/mnt/data/{datetime.datetime.now().strftime('%Y-%m-%d_%H-%M-%S)}.txt"
with open(file_name, "w") as f:
f.write(str(sensor_data))# Wait for the next logging interval
time.sleep(60) # 1 minute interval
```
### Example 2: ESP32 Camera Module Image StorageIn this example, we'll use the SanDisk 32GB Micro SD-SDHC Memory Card to store images captured by an ESP32 camera module.Hardware RequirementsESP32 development board (e.g., ESP32 DevKitC)
SanDisk 32GB Micro SD-SDHC Memory Card
ESP32 camera module (e.g., OV7670)
Breadboard and jumper wiresSoftware RequirementsArduino IDE (latest version)Code Example (C)
```c
#include <SD.h>
#include <esp_camera.h>// Set up the SD card
SD.begin();// Set up the camera module
camera_config_t config = {
.pin_pclk = 25,
.pin_vsync = 12,
.pin_href = 13,
.pin_sscb_sda = 26,
.pin_sscb_scl = 27,
.pin_pwdn = 32,
.pin_reset = -1,
.xclk_freq_hz = 20000000,
.ledc_timer = LEDC_TIMER_0,
.ledc_channel = LEDC_CHANNEL_0,
};
esp_err_t err = esp_camera_init(&config);
if (err != ESP_OK) {
Serial.println("Camera initialization failed");
return;
}// Capture an image
camera_fb_t fb = esp_camera_fb_get();
if (!fb) {
Serial.println("Camera capture failed");
return;
}// Create a timestamped file for image storage
char file_name[32];
sprintf(file_name, "/sdcard/%d.jpg", millis());
FS_Info info;
SD.mkdir("/sdcard");
SD_FILE file = SD.open(file_name, FILE_WRITE);
if (!file) {
Serial.println("File creation failed");
return;
}// Store the image on the SD card
size_t written = 0;
while (written < fb->len) {
written += file.write(fb->buf + written, fb->len - written);
}
file.close();// Release the camera frame buffer
esp_camera_fb_return(fb);
