De Fumar Posted April 17, 2004 Share Posted April 17, 2004 I've been toying with the idea of setting up a pc to monitor the conditions in my growroom. No fancy stuff like switching fans on and off or nutrient dosing, just logging temperature and humidity to a database or excel. The part I am finding difficult is sourcing a thermometer and hygrometer that will attach to my pc, a quick search for a usb thermometer on Google comes up with nothing except a DIY kit to build your own. Does anyone know of any USB devices like this, or does anyone have a similar system in place? After a few hours of searching, all I could come up with was this.

mickle Posted April 17, 2004 Share Posted April 17, 2004 The i-button 1 wire system perhaps? http://www.ibutton.com/ They have "thermocrons" and a boat load of other stuff ("weather station"). When I looked into it it was about £20 for a thermocron and an PC interface so quite cheap. There is an api for programming languages too IIRC.

De Fumar Posted April 18, 2004 Author Share Posted April 18, 2004 Nice one Mickle, surely one to consider. It would be interesting to know if anyone has used the i-button devices before....... I'm still very surprised that nobody makes a simple USB thermometer, it would be useful for keeping an eye on server room temperature, never mind growroom temp.

Spliffy. Posted April 18, 2004 Share Posted April 18, 2004 I have a computer monitored grow room...sort of. I sit at the computer all day, and 4 feet to my left is my GR, being constantly monitored by moi Link to comment Share on other sites More sharing options...

Totally agree DF, I can't find anything on the web that will do this simple job, think you may have found a 'hole' in the market, better patent that idea fast.

Nitramkram Posted April 19, 2004 Share Posted April 19, 2004 your on the job spliffy, keep one eye on em and one on the screen. do you have a button or a shortcut for a water ? Totally agree DF, I can't find anything on the web that will do this simple job, think you may have found a 'hole' in the market, better patent that idea fast. I think software material (ie code) would be done by this mob (first URL by De Fumar Posted on Apr 18 2004, 04:21 AM) I'll folow with interest - I'm over being a programmer but like 'databases' (MS Access & SQL & Note Books ect) now into Network Administration & Networks Link to comment Share on other sites More sharing options...

Guest Red Dragon Posted April 22, 2004 Share Posted April 22, 2004 For any sort of environmental logging, look no further than your local Maplins Electronics store...or online, under the "PC based data acquisition" heading! RD Link to comment Share on other sites More sharing options...

eltony Posted April 22, 2004 Share Posted April 22, 2004 I've got some control and monitoring plans for the new grow room design, currently i'm only on my first grow (in a NFT 205) but i've really got the bug for it now..........Anyway I think i'm going to build a gully type ebb and flow system, and control the fans, lights, and pumps with a PIC microcontroller and hook that up to the parallel port of my Linux PC (then I can write a nice interface ) along with temperature and ph monitoring. This in combo with a time-lapse webcam video B) The reason for overdoing it so much is that is like to be able to do flushing automatically (its all about the automation!). I'd like two tanks one for ph adjusted water and one for nutes, and then T-junction's and solinoid valves to control where the water comes from (and returns to) This will mean I need two pumps, but there not that expensive and i've allready got one. This is more of a long term goal though and I intend to do this after everything else. Its all a bit complicated and it won't all happen at once, but i've got all summer at my disposal Link to comment Share on other sites More sharing options...
