Turn your phone into a connected OpenXC platform.
The OpenXC Dweet application serves a number of functions. It is a bluetooth-enabled data collector, that wirelessly connects to the installed VI and samples incoming data. It can then store that data locally or transmit it, real-time, via the phone's cellular data connection, to the dweet data store. In addition, it can capture sensor data originating from the phone itself (e.g. GPS), and include that in the data stream.
