Greetings to all - I'm a first time poster, and a total newb to arduino. I got a starter pack as I've always been interested in learning more about electronics and programming and have been hooked. Having done some projects, I think I'm ready to try something a bit more complex.
While I've seen that there are a lot of options when it comes to using moisture/temperature sensors to monitor potted plants, hydroponic gardens, or greenhouses, I haven't been able find any options for monitoring a relatively large vegetable garden. As I mentioned, I am a newbie to this, so I don't know what all of the options are for what I'm looking to do. To that end, this is what I'm looking to do:
I have a relatively large garden, approximately 16m (52ft) long by 4m (13ft) wide. The garden itself is located about 20m (60-70ft) from my house. Between the house and the garden, I am building a greenhouse. The greenhouse itself will be about 10m (33ft) from the garden. Schematics are approximate:
| | | GH |
| Garden |
What I want to do is monitor the soil temperature at 3 different points in the garden (perhaps more later). The segment closer to the house gets more sun, whereas as you move away, there is less sun.
I am not sure what the best sensors to use are. I am familiar with TMP36s so far. The cables would have to be very long, especially if I wanted to hard connect to the arduino inside the house.
There is the option of running cables to the greenhouse, then setting up some solar-powered power source (the GH, at this point does not have power from the house) and using a wifi shield to connect that way to computer indoors.
I'm looking for other options or the optimal option, which I hope the arduino community can help me out with.
