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.
