Star Wars Lunch Box Data Aquisition

I used a Raspberry Pi 2 to make a mini data acquisition system that fits inside of a lunchbox.

About this project

The intent for this project was to make a data acquisition system that is easy to use, and can be portable.  The system is self contained and can connect to internet via Wi-Fi.  There is a built in battery that makes the system able to be transported to virtually anywhere.

There were three sensors used from the Esplora board: a temperature sensor, an accelerometer and a light sensor.  The Raspberry Pi 2B has the ability to take data from each of the sensors simultaneously.  The data can then be emailed to any email address via Wi-Fi, or simply stored in the 32GB Micro-SD card.

Code

Esplora CodeJava
This is the code required for the Raspberry Pi 2B to be able to read each sensor on the Esplora.
#include <Esplora.h>

void setup()
{
  Serial.begin(9600);
  Serial.println("STARTING!");
  Serial.println("-----------------------------------------------");
}

void loop()
{
  int sensorValue = Esplora.readLightSensor();
  
  float voltage = sensorValue * (5.0/ 1023.0);
  
  Serial.println("LIGHT_SENSOR: ");
  
  Serial.print(voltage);
  Serial.println("");
  
  int f = Esplora.readTemperature(DEGREES_F);
  Serial.println("TEMPERATURE: ");
 Serial.print(f);
 Serial.println("");
 
 
 int x = Esplora.readAccelerometer(X_AXIS);
 int y = Esplora.readAccelerometer(Y_AXIS);
 int z = Esplora.readAccelerometer(Z_AXIS);
 Serial.println("ACCELEROMETER");
 Serial.println("X: ");
 Serial.print(x);
 Serial.println("");
 
 Serial.println("Y: ");
 Serial.print(y);
 Serial.println("");
 
 Serial.println("Z: ");
 Serial.print(z);
 Serial.println("");
 Serial.println("-----------------------------------------------");
  delay(5000);
}
