Modular Design – dense packets of sensors eases installation, management. Miniature sensing element
3.8 cm 2.5 cm 5.6 cm Sensor Manager Communication Module PVC housing glued or clamped dimples for routing wires to sensors Sensor Manager, Communication Module, and batteries shown in single waterproof housing Good performance / size But over budget Design as of early 2002
Proposal 9/21/02 Incorporate new open-source OTS wireless modules to reduce development costs
