Hello …
I am a beginner in arduino Develop … this my first project
i need to send some data from adruino sensor to my server (php script) throw GPRS
i’m using SIM808 GSM GPRS GPS
i try many codes but The moisture values are shown on the serial monitor but still not in the php script. in all of these codes
any one can help me !!
this my code for arduino
#include <SoftwareSerial.h>
#include <Wire.h>
SoftwareSerial mySerial(2, 3); // RX, TX Pins
String apn = "Vodafone"; //APN
String apn_u = "Internet"; //APN-Username
String apn_p = "Internet"; //APN-Password
String url = "http://abozezo959.000webhostapp.com/index1.php"; //URL for HTTP-POST-REQUEST
String data1; //String for the first Paramter (e.g. Sensor1)
String data2; //String for the second Paramter (e.g. Sensor2)
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
delay(10000);
}
void loop() { // run over and over
data1 = "123";
data2 = "ABC";
gsm_sendhttp(); //Start the GSM-Modul and start the transmisson
delay(60000); //Wait one minute
}
void gsm_sendhttp() {
mySerial.println("AT");
runsl();//Print GSM Status an the Serial Output;
delay(4000);
mySerial.println("AT+SAPBR=3,1,Contype,GPRS");
runsl();
delay(100);
mySerial.println("AT+SAPBR=3,1,APN," + apn);
runsl();
delay(100);
mySerial.println("AT+SAPBR=3,1,USER," + apn_u); //Comment out, if you need username
runsl();
delay(100);
mySerial.println("AT+SAPBR=3,1,PWD," + apn_p); //Comment out, if you need password
runsl();
delay(100);
mySerial.println("AT+SAPBR =1,1");
runsl();
delay(100);
mySerial.println("AT+SAPBR=2,1");
runsl();
delay(2000);
mySerial.println("AT+HTTPINIT");
runsl();
delay(100);
mySerial.println("AT+HTTPPARA=CID,1");
runsl();
delay(100);
mySerial.println("AT+HTTPPARA=URL," + url);
runsl();
delay(100);
mySerial.println("AT+HTTPPARA=CONTENT,application/x-www-form-urlencoded");
runsl();
delay(100);
mySerial.println("AT+HTTPDATA=192,10000");
runsl();
delay(100);
mySerial.println("params=" + data1 + "~" + data2);
runsl();
delay(10000);
mySerial.println("AT+HTTPACTION=1");
runsl();
delay(5000);
mySerial.println("AT+HTTPREAD");
runsl();
delay(100);
mySerial.println("AT+HTTPTERM");
runsl();
}
//Print GSM Status
void runsl() {
while (mySerial.available()) {
Serial.write(mySerial.read());
}
}
and this my code for php
<?php
$timestamp = date("d-m-Y - H:i:s");
$datastring = $_POST["params"];
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
$txt = $timestamp . " - ".$datastring."\n";
fwrite($myfile, $txt);
fclose($myfile);
echo $txt;
?>
