    • Texas Instruments 16 bit microprocessor (TI MSP 430)
    • 802.15.4 radio interface
    • Fixed Power Supply via the USB Interface
    • Temperature, humidity and light sensor
    • 1 MB external flash
  • 7 MSB-430 Sensor Nodes
    • Texas Instruments 16 bit microprocessor (TI MSP 430)
    • CC1020 radio interface
    • Temperature, humidity and acceleration sensor
    • SD memory interface

The UBERN testbed hence consists of 47 sensor nodes. The network spans accross the 4 floors of the building.

The 7 MSB430 nodes are placed indoors. Out of the 40 TelosB nodes, 39 nodes are placed indoors, each of them in different rooms or corridors of the building, and one node is an outdoor node placed on the top windowsill of the building's small tower.
