  4. 7.1 x 18.8 mm 3.6 x 6.4 x 9.1 mm 5.6 x 8.9 mm 25 x 25 x 7.6 mm 8.9 x 8.9 x 2.5 mm • ICP • Miniature • Efficient package • Mature design • High frequency / wide bandwidth • as low as 10 mm want DC response, too • MEMS • Cheap sensors • Cheap conditioning • Micro?

  5. Modular Design – dense packets of sensors eases installation, management. Miniature sensing element

  6. Design as of early 2002 • PVC housing • glued or clamped • dimples for routing wires to sensors Good performance / size But over budget 3.8 cm Communication Module Sensor Manager 2.5 cm Sensor Manager, Communication Module, and batteries shown in single waterproof housing 5.6 cm

  7. Proposal 9/21/02 Incorporate new open-source OTS wireless modules to reduce development costs

  8. Building a Digital Model(Metadata)
