I need to know if what i want to do is possible. I am not afraid to learn and to try new things but i am a beginner.
Would like to remotely control a 15 hp irrigation pump. The variable frequency drive (vfd) allows me to control it easily using a couple of outputs. This is what i want.
-control below items using sms
-pump on (flip on an output i can make the pump go myself)
-pump on for certain time frame determined in the text (i.e. 2hr 4hr 6hr up to 12hr)
-send me an sms when there is a problem with the pump or when pump shuts off (there is an output in the vfd that could be used as an input)
-tell me the preasure when requested from an sms (there is an analog preasure transducer already in the system just read me the value)
Okay can i do that?
Also what devices would i need? GSM shield i presume. Which one or does it matter? Ardurino? Uno? Mega? Does it matter? Relay shield?
I am sorry for not knowing this your help is extreemly apreciated!
I think GSM refers to a cellular network. If so, I haven't seen any similar projects ever working out how to run the needed server within the cellular network.

I'm missing something here. As far as I can see, the need in this project is simply to use a GSM module to send and receive text messages and a little bit of IO controlling a pump. Seems quite feasible with a GSM module and an Uno; my only doubt is around the needs for variable frequency drive and that's only because I'm not familiar with it.

No you're. not missing much. The only programming background i have is some fortran and matlab. I. Just wanted to make sure the ardurino and gsm were capable of doing the above menctioned things. I assume from your post that they are.
Does this infact mean that that the ardurino can interpret those different commands from a text? Also can the ardurino run a timmer for 12 hr while recieving other commands requesting feedback? Remember beginner.
Yes, the Arduino would be the correct way to go as you have many unique variables, you can build them into the Arduino program and control pump motors and switches.
I have an Arduino system monitoring and controlling a hydroponic system with GSM.
Andre thanks for your help you seem quite knowldgeable. Does it matter which ardurino i use? Would the cheapest work? Also which gsm shield should i use? Should it be the one made by ardurino or can i use a cheaper aftermarcket one? What are the differences.
