Extendable: Bluetooth, Software Defined Radio, … !! Every node is powered via PoE and can be disabled !! Environment emulator (EE) !! EE can emulate battery voltage of the sensor nodes and can measure the consumed electrical power real time !! EE can emulate environmental variables like switches, monitored data !! EE can log the events of the sensor nodes !! Sensor nodes can measure and react on real and emulated environmental variables !! Development environment !! TinyOS (sensor nodes) !! Click (iNodes) !! Remote access 16
