hola amigos, necesito de su ayuda para poder crear un codigo para enviar desde mi placa Arduino atraves de la placa WiFly datos sobre dos sensores, de temperatura y humedad, luego mandarlos poe Wi-Fi a una base de datos Mysql. Algo asi :
Sensor 1 y 2----->arduino-------->WiFly-------->PhP----->Mysql

El condigo del sensor es este:
Code: [Select]
#include <OneWire.h>

int sensorPin = A0;    // select the input pin for the potentiometer
int sensorValue = 0;  // variable to store the value coming from the sensor
int DS18S20_Pin = 2; //DS18S20 Signal pin on digital 2

//Temperature chip i/o
OneWire ds(DS18S20_Pin); // on digital pin 2

void setup() {
 // declare the ledPin as an OUTPUT:
  Serial.begin(9600);  
}

void loop(void) {
 // read the value from the sensor:
 sensorValue = analogRead(sensorPin);    
 delay(1000);          
 Serial.print("sensor de humedad 1 = " );                      
 Serial.println(sensorValue);


float temperature = getTemp();
Serial.print("sensor de temperatura 1 = " );
Serial.println(temperature);

delay(1000); //just here to slow down the output so it is easier to read
 
 
Serial.print("----------------------------" );                      
Serial.println(" ");
}


float getTemp(){
//returns the temperature from one DS18S20 in DEG Celsius

byte data[12];
byte addr[8];

if ( !ds.search(addr)) {
  //no more sensors on chain, reset search
  ds.reset_search();
  return -1000;
}

if ( OneWire::crc8( addr, 7) != addr[7]) {
  Serial.println("CRC is not valid!");
  return -1000;
}

if ( addr[0] != 0x10 && addr[0] != 0x28) {
  Serial.print("Device is not recognized");
  return -1000;
}

ds.reset();
ds.select(addr);
ds.write(0x44,1); // start conversion, with parasite power on at the end

byte present = ds.reset();
ds.select(addr);  
ds.write(0xBE); // Read Scratchpad


for (int i = 0; i < 9; i++) { // we need 9 bytes
 data[i] = ds.read();
}

ds.reset_search();

byte MSB = data[1];
byte LSB = data[0];

float tempRead = ((MSB << 8) | LSB); //using two's compliment
float TemperatureSum = tempRead / 16;

return TemperatureSum;

}

Arduino no puede conectar con Mysql directamente, tienes que hacerlo mediante PHP y de aqui a Mysql
