1. Fabrication of a Wireless Sensor Network for Extreme Environments EE 496, Fall 2006 By: Faye Yuen

2. Project Overview Design a network of autonomous motes to: Distinguish between water/ice Collect data on environmental factors to supplement any bio-signs found Detect life in extreme environments Contribute to Dr. Chris McKay’s research Prepare the mote network for use in an upcoming expedition to Antarctica Meet the goals of NASA

3. Approach Program motes to ensure functionality in temperature and humidity sensing (and being able to access that information from a computer) Integrate solar cell modules to recharge battery power source Add sensor to distinguish between water and ice

4. Potential Problems Software/Hardware incompatibilities Unfamiliarity with programming code Getting supplies Making motes durable enough to withstand anticipated conditions in Antarctica TIME MANAGEMENT!!

5. Learning Outcomes Improve programming skills Gain more hands-on experience in a variety of applications (ex. networking, communications, power, sensors) Work with client to meet their needs Complete a large-scale project from beginning to end Improve writing and documentation

6. Deliverable Goals Wireless network with temperature, humidity, and water/ice sensors Renewable energy source (rechargeable batteries and solar modules) Robust and durable motes User-Friendly Documentation
