| hads | G: Here | 01:08 |
|---|---|---|
| G | hads: ohhh good news :) | 01:24 |
| G | hads: when you've added it all up just let me know and I'll put the payment in asap | 01:30 |
| ojwb | anyone got any good suggestions for something easy and fairly cheaper for monitoring temperature and humidity in a greenhouse (and ideally outside too while I'm at it) | 01:32 |
| ojwb | ideally without too much hardware hackery as that'll delay it actually happening a lot | 01:32 |
| hads | WIthout hardware hackery your best bet would be an off the shelf weather station thingy. | 01:32 |
| ojwb | i wondered if that might be the case | 01:33 |
| G | ojwb: I seem to recall Jaycar have some nice modular ones, no idea how good etc they are | 01:33 |
| ojwb | doesn't need to be all that precise, nearest degree should be fine | 01:34 |
| hads | I have loads of different options for sensing temerature here, but all require some hackery. | 01:35 |
| hads | Hackery and weather proofing. | 01:36 |
| ojwb | the weather stations seem quite plausible in price and function, assuming I can get a sane data feed out of them | 01:37 |
| G | most o fthe weather stations seem to be closed box solutions, hmmm | 01:37 |
| hads | Data feed = more $ | 01:37 |
| G | Etherten w/ a couple of Temp/etc sensors would be fun, but hackery/etc | 01:38 |
| * ojwb knows karora brought one back from the US or somewhere and got it talking to linux, but I think that was rather higher end | 01:38 | |
| hads | Yeah, the EtherTen is the way I would go. Will have easy to use little temp sensor modules in the next day or two. | 01:40 |
| hads | http://www.freetronics.com/products/temperature-sensor-module | 01:40 |
| hads | http://www.freetronics.com/products/humidity-and-temperature-sensor-module | 01:40 |
| ojwb | hads: any idea of likely NZ prices? | 01:42 |
| G | hads: the second one looks neat except for one thing.... blue LED | 01:42 |
| ojwb | comms and power over ethernet should significantly reduce the amount of hackery required | 01:43 |
| ojwb | and I think I can remember which end of a soldering iron to hold | 01:43 |
| hads | G: Screwdriver will take care of the LED :) | 01:43 |
| G | hads: haha | 01:44 |
| hads | ojwb: Let me finish what I'm doing and I'll work out the prices. | 01:44 |
| ojwb | -4 to +125 C is a little tight on the lower end for this application | 01:44 |
| G | The EtherMega's look neat, but I don't really have a need for Ethernet for my project | 01:44 |
| ojwb | on the combo one | 01:45 |
| karora | ojwb: It was a Davis Instruments. | 01:45 |
| hads | ojwb: The DS18B20 should have a better range. | 01:47 |
| karora | Anything with a decent rain gauge costs significant money. The Davis is at the cheap end for full function weather stations, though there are some Oregon Scientific or La Crosse which cost fewer $$$ per weather station - you will just find that they don't last as well. | 01:47 |
| hads | ojwb: -55 to +125°C | 01:47 |
| ojwb | hads: yeah, but that doesn't get humidity, so you need to choose between them | 01:47 |
| ojwb | or buy both | 01:48 |
| karora | I had a friend who bought a wireless weather station (rain, wind, temperature, humidity, barometer) for around $220 which connected to his computer via serial. | 01:48 |
| karora | The rain gauge had a capture area of about 10 cm2 - not really enough. | 01:48 |
| ojwb | i think rain fall isn't so interesting for me | 01:48 |
| ojwb | it's NZ, I know it rains a lot | 01:48 |
| karora | Well, you know it's windy too. | 01:49 |
| ojwb | indeed - mostly I want to know if the greenhouse is too hot or too cold | 01:49 |
| karora | If you just want temperature / humidity / barometer I can sell you my old La Crosse. | 01:49 |
| ojwb | if the readings stop, that'll tell me if it's too windy and it has blown away | 01:50 |
| karora | It has a serial port interface which I used with a USB Serial. | 01:50 |
| ojwb | got a link to the specs? | 01:50 |
| karora | And it's well understood by Linux. | 01:50 |
| G | hads: there is a cable missing no? | 01:51 |
| hads | G: There is? | 01:52 |
| G | hads: shouldn't there be a 3rd 7.5m? | 01:53 |
| hads | Oh dear, that day was a bad day, that's the third thing I messed up for you. | 01:54 |
| hads | Was confused by the purple fiasco and didn't order a third. | 01:54 |
| hads | I did order a 15M if that would suit? Or I have a blue 5M? | 01:55 |
| G | yeah, that was my fault, I assumed they were common lengths in all colours etc, let me just check something | 01:55 |
| G | I might take the 15M, let me just check how long the cable to my HDHomeRun is | 01:56 |
| karora | ojwb: I think it's a WS3510. I also have a WS3502 but the anemometer needs replacement. | 01:56 |
| G | hads: yeah okay, bill me for the 15m, I'll use the 10m cable the HDHomeRun has instead of the 3rd 7.5m, and the extra 5m can be coiled out of the way for the HomeRun | 01:58 |
| hads | Done | 02:04 |
| G | hads: replied! | 02:10 |
| G | hads: thanks, and sorry for been such a pain | 02:10 |
| hads | Not a pain at all. | 02:11 |
| ibeardslee | those the gold plated super thick HDMI cables? ;) | 02:20 |
| ajmitch | the ones that deliver a superior digital experience? :) | 02:22 |
| G | ibeardslee: you mean those $200+ Monster cables? I take great pleasure in telling sales people that they aren't going to fool me on that sorta stuff :P | 02:24 |
| ibeardslee | I think one day I might lead someone on with that and then as they are ringing it up say .. actually I'll take one of these $15 jobbies | 02:27 |
| ajmitch | what a way to crush their hopes | 02:29 |
| ibeardslee | morning | 19:02 |
