Are you an Arduino enthusiast? Arduino is an easy to use electronic rapid prototype framework that lets programmers able to easily approach to the fantastic world of physical computing.
INGEGNI Tech S.r.l. played with this tool and implemented an iPhone/iPad application, targeted to Apple and Arduino enthusiasts, that could be used to display the real time value of environmental temperature, pressure and humidity.
The required working set is not complex. All that you need is an Arduino UNO board and two "shields". The first (Ethernet Shield) lets Arduino able to communicate through the ethernet cable; the second lets Arduino able to read environmental pressure, temperature and humidity. You have then to program the Arduino UNO board with the sketch we released here:

The last step is to open the iPhone application and to specify the Arduinos IP address. Temperature, pressure and humidity values will be shown in realtime. Thats amazing!
As you can understand, the values are published by the Arduino internal web server and they are available whatever is the place where the network is available.
