I want to be able to record outdoor temperature on my PC (and be able to
stick the temp on my website etc.) but I don't want to have to buy a
full weather station for £hundreds. I also have no way of mounting
anything as I'm in University accommodation, so have to make do with
dangling something out of my window (which conveniently enough is nearly
always in shade). Something that could connect to the serial port would
be ideal.

Does anyone have any ideas about what I could do? I could knock
something up myself as I have access to a soldering iron and whatnot,
but a premade option would be best.

I hope to be able to get something better when I move into my own house
eventually!

Thanks,

Interesting idea!

Id be interested in any replies to this.

I have broadband (always connected) with an Apache webserver running on my PC.

It sounds a nice idea to put a temperature-reading of my back-garden on the web.

One of these is what you want

Well depends whether you want free or low-cost. For a couple of the
latter look at:

http://www.drdaq.co.uk

and

http://www.techsupplies.co.uk/ (and search for 'weather station')

I've not seen or used either, so this certainly isn't a
recommendation, just information. I suspect that the former in
particular is just 'school-grade'. The 1-wire products have a better
pedigree. You'd still need to do a little development with the
software I guess, but at least you shoudl be able to get the data into
a PC with either.

If you're handy with a soldering iron, you may
also want to look at the Aug and Sep editions of
Everyday Practical Electronics.

I'm going to try something from Maplin first (£5 so probably isn't too
accurate etc., but I'm ordering something else from them at the same
time) which might work for the next year or so. I'll let you know how/if
it works; I'll also let you have any code that I need to write to get it
to work on my website.

There was a project in EPE a few years ago to build your own weather
station. I still have the issues somewhere and might give it a go when
I've got time/money to hand.

Jonathon,
have you thought about the datalogger route. I have used a Digitron Monolog
single channel temperature logger which can take readings every, say, five
minutes. It is wireless, compact, so can be stuck anywhere. Then bring
indoors at required interval (weekly, daily etc) and download via serial
port to PC. Software allows graphical presentation of data etc. Only
drawback might be precision only quoted at +/- 0.5C.) If you want more info
or possible loan then e-mail me.

I really want 'live' temperatures (so I can find out how cold it is at
home from my lab office).

I have a number of assembled units which accommodate up to 16 Dallas
DS18S20 temperature sensors on a single twisted pair. The interface
is 9600 baud RS232.

TM #125 - Single Dallas DS18S20 Run
TM #127 - Two Dallas DS18S20 Runs plus programmable output.
TM #128 - Two Dallas runs which will accommodate DS18S20, DS18B20,
DS1822 and DS2438.
