Project OverviewWe are using an Interface board,
4 RF boards , and 3 sensor boards to create a
ad-hoc wireless network that could be used for a
variety of applications.Ad-hoc wireless
communications not only from base station to an
individual unit, but also communications between
the units themselves.Crossbow company who
designed and made the equipment we are using, the
MICA Motes.TinyOS a small operating system
designed for wireless networks developed at UC
Berkeley

Revised Goals

• Learn the characteristics of existing sensors
  through data sheets and through testing
• How can we interface new sensors?
• Create Motes for Dummies II ( guidebook for
  future groups )
• Demonstrate Ad-Hoc wireless capabilities

Equipment Testing

• Light sensor functionality
• Transceiver functionality
• Problems encountered handling data from sensors,
  also magnetometer wasnt responding.

6
What is next

• Verify functionality of the rest of the sensors.
• Verify ad-hoc radio link is working correctly.
• Handle the data the sensors provide.

Gantt Chart

• Getting Started We completed the Motes for
  Dummies I manual and verified functionality of
  the boards, and reviewed many different sources
  of information.
• Review and Testing Verified the functionality of
  the boards. Sensor testing, RF testing,
  interfacing with the computer. Also becoming
  familiar with pre-existing capabilities, as well
  as what possibilities are.
• Software modification and testing Fixing
  problems in the previous code so that it works
  for our applications. We will be programming in
  NesC, using TinyDB, and creating and using
  interfaces.
• Hardware sensor design We plan on making
  providing information to the next group as to
  what kind of sensors they could design that could
  be placed on a generic sensor board.
• Revision Solving unresolved issues, putting it
  all together.
• Demonstration Show off our final project.
• Documentation Keep track of our work in lab
  notebooks.
