So I'm doing a project that involves getting sensor data from several sensors, and then sending them to an external server when a tragic occurs. But I've been having trouble figuring out how to send this data, and I am welcome to advice (I'm still relatively new to Arduino coding).

I'm using an Arduino mega, with a sim900 GSM shield and an SD card. The sensors are just analog reads and a GPS.

I've looked into FTP, a Xively account and http requests to a web server but couldn't figure it out.

  • Do you have internet service in that GSM shield? – fabrosell Mar 30 '16 at 21:21
  • Yup. The shield has a SIM card with 3G – Generalno1 Mar 31 '16 at 2:15
  • You should check for: "Sim900 HTTP POST" on Google. There also should be a lot of libraries for this. You'll have to set up a webserver that accepts HTTP post messages. But you might try using a post dump test server first (posttestserver.com) this worked great for me in the past. But I had an PIC microcontroller. – Paul Mar 31 '16 at 9:12

There is a good example of using the SubmitHttpRequest() in this article: GPRS Shield SIM900 Arduino

You could easily modify: mySerial.println("AT+HTTPPARA=\"URL\",\"www.yourwebsite.com/testing.php\"");

to include a string of the sensor value, and then using a PHP script to MySQL on your webserver. Maybe something like: http://yourwebsite.com/testing.php?sensor1=5&sensor2=10
