recording temperature data and downloading to the cloud

Any one got any experience with recording temperature data and uploading the results to the cloud so it can be accessed remotely.

you can see this software on my blog i use it to send water level to cloud from serial ports "USB", if you need the code just tell me, with some editing you can use it for temp, anyway i build it to send any data to cloud, with other third party software, or you can download ready library for cloud & use it with this app

You can do this with Xively. You get two libraries from them and two passwords. It involves just a few extra lines of code. There are other options, like Grovestreams.
