Terrarium control system
    #1237722 - 01/21/03 06:41 PM (18 years, 10 months ago)

For those of you who are interested, I've finished my first control system. It works fine, just as I had planned, and I've documented everything in the process of making it on this site

There are complete design plans to build your own, and although it requires some electrical expertise to do this, I am willing to make units for other shroomerites who are interested in precise, automated control of their fruiting chamber's conditions.

The unit has many uses. It can automatically turn fans on for a set amount of time for air circulation; It can turn on your humidifier when the humidity drops below a certain percent RH; It can heat or cool your chamber. All of this is done through a PC's parallel port, and the software has been tested on Windows XP and 2000.

Just drop me a line (via. PM) if you have any questions or are interested.

*jaw hits floor*

Wow, that's awesome! I've had something like this nagging the back of my mind for a while, but I'm a software geek, not a hardware geek, and I didn't even have a clue where to start. Thanks to your page I can hack together some parts and pretend like I know what I'm doing, and possibly even get a working terrarium control system out of it. Thanks!

Nice layout... did you use mentor graphics? Been a while since I worked with it, but those are what our printouts used to look like.

Yes, that's very cool! Tell us how much will it be!
Another question:
What about the protection of computer from the high currents on relays?

What do you mean? Any high current from the switching side of the relay is isolated from the rest of the circuit. The relay has a diode across the coil protecting that side of the circuit. I don't see a problem here in the design.


(Mentor graphics is an EE cad, digital design and modeling program, not a graphics drawing program. Nice artwork.)

i have access to a rapid prototyping circuit board machine

basically, its a CNC router that makes/drills double sided circuit boards.

if you draw a layout, i might be interested in making some up.

just depends on the popularity of this idea!

Thats alot faster than me running down to radio shack and making a few.
I mentioned this to some other guys and I know of at least 4 ya could sell.

I don't know much about electronics & terminology that's why I'm asking this.
I meant optical isolation between high current side and the logic side. Would that make things much more expensive? I'm wondering what are the chances that I fry my computer if I switch currents of 3A or 5A? Is that diode in relay enough?

A relay is a magnetic controlled switch. The high current side has no physical contact to the control side. The control side is simply a magnetic coil that pulls the switch closed when the coil is charged. A spring opens the switch when the coil discharges. The only concern is that the energy stored in the coil has to go somewhere when discharged. The diode takes care of that little problem providing a one-way path when needed.

>here's two products that do the same thing

Can you attach a humidity and temperature probe on these?

I don't think these will let you do that.

But someone told me about a switch they make and sell at lowes that is made to open valves it's runs of moister in the air is suposed to have a setting ajustment.

I dunno though I'm going to hunt for this in a few hours. If i find it i'll let you know.
I hope if i can find it.
If it will set right is the ? though.


I plan on doing a mock setup with some extra dung/straw I had left over from the last run.
This way I can see if it will let me control it without the cause of losing a crop if it doesn't work out.

Well lowes doesn't have it. However I have located one I think.
I asked a guy with a plumbing shit on about them. He told me where to get them at a plumbing shop downtown.
He also clames they make one that will read humidity and cause it to open or close depending on how u set it.

He wasn't sure of the exact name so I'll be hunting again tomorow.

I did see something at a pet store it was called a "FROG HUT"
the lady said it will keep humidity at any level you set it at same with the temp.

Mesurements on it were roughly 17x34x14
It has top mounted auto fans that will come on and bottom vents about 6 inches up.
Downfall to this thing is they want 175.00 + another 100 for the stand.

I think i'm gona fig out the switch thing b4 i spend that much on a frog hut that might not work.

good point, but it can be used to switch things like apliances, and such, via computer.

I didn't know that the circuit also monitored the humidity and temp, sorry, i read over that. I did go to the page, but just missed that part.

and i do think that the x-10 control systems have input sensitive modules.

I had this idea for ages (I'm in tech school, finished telecom going in to automation (climate control :smile:) The only thing that stopping me is the actual humidity and temp sensors.... Anyone knows a better deal ?
