Button boxes are made by Intel as a simple housing with user interface extension for MICA2Dot Motes. A MICA2Dot Mote can be plugged into a button box. There are also two buttons, three LEDs and a buzzer in each button box to provide basic user interface capabilities.
We have deployed 10 button boxes along a hall way on the 11th floor of the ISI office building. These nodes are the building blocks of the "Follow Me" application, which is a sensor network project being developed at I-LENSE (more information coming up soon). We plan to eventually deploy about 70 button boxes on the 11th floor.
