Project Results
Project Goals
  • Range testing included indoor, outdoor, and
    under
  • furniture settings.
  • The effective range of our product is determined
    by
  • our ability to hear the buzzer from wherever
    the tag
  • is located.
  • Pending memory constraints on our
    microprocessor,
  • our design allows us to have up to 128 tags.
  • 3-inch Monopole Antenna
  • On the average for our testing, we found that
    there
  • was a received power of -90 dBm.
  • We are transmitting at 4 dBm.
  • The average current drain on our tag is 6.78 mA.
  • 916 MHz Ceramic Chip Antenna
  • Through the received signal strength of our
    receiver,
  • we were able to determine that this antenna
    has
  • Item locator utilizing RFID tag and reader
  • 15 meter receiving range
  • Able to drive a DC activated buzzer
  • Multiple tag capability
  • Keypad user interface

Project Overview
  • Reader for transmission
  • Tag with speaker

Project Conclusions
  • Our tag produces the desired results of beeping
  • when sent the right code.
  • We selected components that led to a simple
  • design and reduced production costs .
  • Include a LCD for better user interface on the
    reader
  • Implement a wake up circuitry to conserve power
    to
  • extend the life of the tag
