I have a small hydroponic system set up in my garden which im about to convert to a aquaponic system.
Around a year ago I explored automation possibilities and Arduino came up as the best solution. I've been abroad for some while
so now I'm picking up where i left.
In the aquaponic system i want to measure certain levels:
- Water level
- Dissolved Oxygen
- and more over time. anything that can be measured digitally
The idea is that i measure these numbers and that i'll be able to read them through the internet from any computer or android device around the world. I also would like to be able to control motors for opening up windows in the greenhouse, open water taps, release water from the system and releasing nutrients & minerals.
So i'm looking for advice what to buy? which shield do i go for? the UNO seems to simple?, the MEGA has no ethernet capabilities?, the ETHERNET seems small? Do i go for a board not build by arduino, all these questions.....
please help me to buy what i need to automate this future system
edit1: so after some reading and correct me if im wrong, i will hookup a UNO or a MEGA to a GSM shield. these two will operate in a different location then mine, but are connected to the 3G and GSM network. My idea is to host a small webpage for myself where i can read the data (see above) in my greenhouse system and if needed manually adjust through just pushing some down and up arrows. ( i guess that webpage requires some scripting) But for most of the time the whole system will just operate on itself, adjust nutrient levels, temperature, humidity, oxygen.
