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:
#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;
}
