The SensorScope project is a collaboration between environmental scientists and hardware/software engineers at EPFL. It will consist of two large-scale outdoor sensor networking deployments, the first on the EPFL campus, and the second on an alpine glacier. The aim of these deployments is to measure key environmental quantities at high spatial resolution, for the purpose of modeling and understanding energy exchanges and balances at the earth/atmosphere boundary. The goal of this demo is to show SWeaS (the SensorScope Weather Station), a complete weather sensing unit that we have developed in the scope of this project. SWeaS is the core component of SensorScope and will be installed at over one hundred locations in each of the two deployments. In comparison to previous weather boards designed for mote-class nodes, the design of SWeaS considers the entire chain of requirements for a scientific atmospheric measurement campaign, including packaging, energy autonomy, sensor placement and a diverse set of sensors.
