The Sensing Platform was originally developed by the members of the FAMiLab Hackerspace in Orlando, FL as part of the 2011 Greater Global Hackerspace Challenge sponsored by element14. As they describe it:
The Sensing Platform is a set of hardware and software tools that allow students, educators, researchers, and “makers” to easily collect data from multiple, disparate sensors, and then transmit the sensor data into a “hub” which allows for easy display, graphing, and logging of the sensor data. The Sensing Platform and its components are useful in school laboratories or anywhere sensor data needs to be collected as part of a learning process.
The project is open source, and utilizes Arduino and Processing. Here are links to the code for both hub and nodes and the bill of materials. They plan to offer this project in both kit and preassembled form in the future.
