This weekend I built a simple temperature sensor with #arduino  and got it sending information to #cosm  via the #gsm  shield, using the #bluevia SIM for data. Even after a year working on this project, this was actually the first time I was able to test the whole thing end to end myself, as a user would do (including purchasing the shield and the Arduino kit itself through online store, activating the SIM and adding balance to it, etc...). The results can be seen below and here: where you can get an updated feed and graph of the temperature in my living room. It's a pretty simple project but especially since I have been swanning around London telling people how easy it would be to build a connected temperature sensor with this shield, it was gratifying to see that I was right. :) The project uses the Cosm libraries and is built on top of the Cosm example code, but uses the GSM libraries instead of the Ethernet shield ones. In putting it together I realized one of the differences between writing an IoT application for the GSM shield (as opposed to Ethernet or Wifi) will be keeping data volume to a minimum. Also the Cosm example code just activates the network and keeps it active even when the Arduino is just sitting idle, whereas on GSM you'd want to connect and disconnect, especially if you are on battery power.

Daniel - will you demo this at the IOT London event on 9th April?
That's the plan, assuming we can get on the program. :)
Looks fascinating, great work ... how open a platform is cosm?
It's a good question and one that I was discussing today with +Jeni Tennison over at the Open Data Institute. As far as I can tell there is no explicit way to license your data via (eg) a Creative Commons license. So in that sense I'm not sure it counts as "open data." However, the service allows anyone to upload data and anyone else no download that data - with the focus being on the Internet of Things.
Looking to use this for a medical device project. On Github now looking at example code. Would I have any problem using the shield in the US (FCC approval)?
Keith that sounds really cool - I don't think you would have any problem with using it in the US but I am not an expert on FCC approval issues. I do know Arduino are planning to make it available through their US resellers...
