temperature and humidity monitors/recorders

Can anyone recommend temperature and humidity monitors/recorders to use in my new greenhouse?
I would like to be able to record the temperature and humidity over time to see how it effects the date I can plant seeds etc. a multi point recorder would be nice or a few single point ones as I would like to record inside/outside air and ground temperatures and humidity plus maybe internal/external water butt temperatures!

Thanks in advance,
Mel.

Arexx make some sensors that transmit (wirelessly) to a base station, and from there you can capture to PC. Make sure you get the higher powered one if in a remote greenhouse, my experience is that even with the base station on a windowsill with uninterrupted line-of-sight except for a hedge it was touch and go at the advertised distance,

That will give you real-time logging, for after-the-fact logging I use USB loggers. Plug into PC and CONFIG (interval between readings etc.), carry them to the monitoring location, press the button, retrieve then after a while and plug-in and download the data.

You can get Temperature and Humidity ones, and shop around for price, this just picked at random from Google:
