I have started putting together my greenhouse project. I am currently running a tempreture and soil humidity sensors throughout my greenhouse in my allotment. I am trying to find a way where I can use my GSM900A to transmit data to and from my allotment either to a local server at home or directly to the blynk app.
My allotment doesnt have any power or wifi to connect so I have managed to install power via solar and hooking up some batteries but I am struggling to find any code related to sending and receiving data via GSM900a.
Can anyone help with my project?
