Contact: pd1352@vt.edu, seagreen@vt.edu, vlohani@vt.edu Conclusions  Adding additional water monitoring sensors (wireless sensor network)  Introducing module on analysis of solar energy conversion in EngE 1024 to complement Sustainable Energy Design Project (SEDP) that students complete in the course  LabVIEW programming language gradually integrated in a freshman engineering course, EngE 1024, Fall ’07 – Spring ’10  Students develop LV programs and are provided with data acquisition code  LabVIEW Enabled Watershed Assessment System (LEWAS) developed  Collected data used to raise awareness of environmental sustainability  LEWAS was transformed from a desktop version in to a system capable of real- time monitoring using a field deployable, power efficient embedded computer  System indoor function verified: real-time streaming to EngE 1024 students (Fall ‘09) and outdoor deployment to impaired stream (to be completed S’10) Virginia Tech’s campus; site indicated by star Future site of deployment (planned completion, May ‘09). Mounting poles in place, solar panel, batteries and wireless to be installed Access to real-time environmental data can enhance my awareness and curiosity about environmental issues such as the state of an impaired stream that runs through campus.  LabVIEW can be used to provide students with real-time environmental data from an impaired on-campus stream and enhance their environmental awareness  Themes extracted from qualitative analysis of in-class survey data: An appreciation for real world LabVIEW applications and its real-time benefit. An understanding of Virginia Tech's watershed and where local water flows.
