Graphing sensor data using sd card

Projects Programming

Sorry I forgot to post my code:

#include <SPI.h>
#include <SD.h>
#include <Wire.h>
#include <HIH61XX.h>

HIH61XX hih(0x27, 8);
File myFile;

// change this to match your SD shield or module;
//     Arduino Ethernet shield: pin 4
//     Adafruit SD shields and modules: pin 10
//     Sparkfun SD shield: pin 8
const int chipSelect = 4;

void setup()
{
 // Open serial communications and wait for port to open:
  Serial.begin(9600);
  Wire.begin();
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }


  Serial.print("Initializing SD card...");
  // On the Ethernet Shield, CS is pin 4. It's set as an output by default.
  // Note that even if it's not used as the CS pin, the hardware SS pin 
  // (10 on most Arduino boards, 53 on the Mega) must be left as an output 
  // or the SD library functions will not work. 
   pinMode(SS, OUTPUT);
   
  if (!SD.begin(chipSelect)) {
    Serial.println("initialization failed!");
    return;
  }
  Serial.println("initialization done.");
}

void loop()
{
  //  start the sensor
  hih.start();

  //  request an update of the humidity and temperature
  hih.update();

  Serial.print("Humidity: ");
  Serial.print(hih.humidity(), 5);
  Serial.print(" RH (");
  Serial.print(hih.humidity_Raw());
  Serial.println(")");

  Serial.print("Temperature: ");
  Serial.print(hih.temperature(), 5);
  Serial.println(" C (");
  Serial.print(hih.temperature_Raw());
  Serial.println(")");
  
     myFile = SD.open("Temp.txt", FILE_WRITE);
  
  // if the file opened okay, write to it:
  if (myFile) {
    myFile.println(hih.temperature());
	// close the file:
    myFile.close();
  } else {
    // if the file didn't open, print an error:
    Serial.println("error opening temp.txt");
  } 
  
  myFile = SD.open("Humidity.txt", FILE_WRITE);
  
  // if the file opened okay, write to it:
  if (myFile) {
    myFile.println(hih.humidity());
	// close the file:
    myFile.close();
  } else {
    // if the file didn't open, print an error:
    Serial.println("error opening humidity.txt");
  }
 
  delay(5000);
}

This is just for logging the humidity and temperature to different files on the sd card.
