We use Azure's open source SDK for Node.js, the REST interface of Azure Service Bus and Node.js and Web Sockets Support on Azure Web Sites to illustrate how to capture data from sensors connected to a Pinguino board on a Raspberry Pi running Linux. This is part of Jose Miguel Parrella's presentation at LinuxFest Northwest 2014 in Bellingham, WA.
