Controllers•Minimal processing demands, handshake with
modules, poll device status
• Low Power, Low Cost
• Arduino
• Open Source• Scalable• Strong Documentation on interface with RF devices
•Other controllers available from TI, Amtel, etc.

Power
•Base Station:
•AC
•If possible make it portable with battery power
•Modules: Battery Power
•Want to minimize power consumption
•Small Battery controller and regulator

Human Interface
•LCD screen to give the user feedback on system status and operation
•USB interface with computer
•Possible expansion : addition of modules without the need of a computer
•Alerts with sound and vibration

Sustainability• Parts could be made from multiple
manufacturers.
•Open source micro-controller platform that is available from multiple companies.
• Limited number of moving parts, modules could be bought separately if individually lost.
•Wireless standards will be used for communication.

Safety and Regulations•All communication protocols will fall
within the requirements of the FCC standards.
•All voltages of the system will be <15 V
•Users will not interact with any power systems greater than the power that comes from a wall socket.

Risk and Contingency•Small Team
•Scalable project that can adapt in feasibility
•RF Communication and Identification Issues
•Use of wireless standards, software solutions to identify our modules from general RF noise
•Unexpected hardware/software problems
•Online documentation, built in overhead for hardware failure, Instructors and TA’s
