Intro: The Hydroponic, Automated, Networking, Climate Controlled Greenhouse Project Update (July 22, 2012)

This is a quick update to show what I've accomplished so far in the construction of my greenhouse. As usual I'm far behind schedule mainly due to weather, landscaping projects, work, etc. It's hard to find the time right now to write full instructables on my projects with the level of detail that I try to provide. I expect to have the hydroponics system as well as the climate control equipment installed and in working order just in time for the end of the growing season :( The programming however, is waaaaay over my head for the moment and I believe I'll be working on that all winter long.

I will try to make another one of these update slideshows in 1-2 months when I hopefully have a lot more done. Shortly after that I will try to write detailed instructables on how I did it all. Please subscribe to stay tuned.

I hope I've provided enough information in the details of the photographs. As always, if you have any questions, comments or constructive criticism I'd be happy to hear it. Thanks for looking!

As a network engineer, this project makes my giney tingle. If you need help with the code, or would like to collaborate feel free to contact me on Twitter @WithWhitt. I have plenty of free time (medically retired).

I didn't even think of running power over ethernet using a 66 block and relays. I had the idea to use a PoE switch but transforming and stepping down the voltage is more hassle. This looks genius!

Do you have a schematic for the plc that you can share?

Has this project continued or died off?

Hi,

What brand is the big enclosure you are using? the one with the transparent front door.

Thank you.

Hey I was wondering if you had a material list and as well the arduino code?

Congrats, you should be proud! I don't know much about construction work, carpentry, let alone gardening, but I'm fond of your electronics - looks very professional, well-thought and clean; some industrial controller designers could learn from you :).

Could you please for me refer this detail your poject? I like it. I like box control panel by arduino. I don't know how to make it. Please for me refer. thanks so much.

Congratulations for your project.

I want to ask you what type and size of wires are you using on your project!

I want to connect my arduino mega to my gsm shield,keypad,lcd and i dont know what type fo wire to choose

Very nice work. how have you come along with the programming? I am a C++ developer and just about to embark on a similar project myself. Im intrigued as to why you used those large relays when you have 16 available rated at 10A/250V AC? Also, what is the item next to the large relays in the middle of the unit? Couldn't figure that one out :)

Hi. Because of time and budget issues and because of an epiphany that simpler is better I have abandoned this project in favor of a passive solar greenhouse. I recently bought a large lot of land in the country and will eventually build a homestead and move there.

The reason I used the large relays instead of the ones built into the blue board is that the blue board is not UL listed or CSA approved and I don't trust them with 120 VAC. Instead, the blue board relays are used to switch the 12VDC coil on the larger relays which are UL listed.

That small green thing that you asked about is another relay. It's used to activate the big motor contactor beside it. The motor contactor has a 120VAC coil so again, I didn't trust those blue board relays with 120VAC so the blue board relays activate the small green realy which activates the motor contactor.

Hope this helps! Let me know if you have any more questions and good luck on your project.

Thanks for the info, I can see the logic behind using more heavy duty relays now. ah, thats a shame to hear you've dropped the project. Well if you need any help with that kind of programming feel free to drop me a message in the future

Hi,

I'm quite interested in your greenhouse project and have a question for which I can't seem to get a clean answer.

Where do you place the temperature sensor, inside the greenhouse? And how do you protect it from the sun, and moisture / wind?

i.e. how do you know the temperatures reported are accurate, and not affected by the elements?
