M1-Mini Skyeteks RFID Reader/Writer Module.
Introduction

• Miniature 13.56MHz OEM RFID reader/writer module.
  
• On-board (internal) antenna.
• 7cm read range.
• Reads, writes and identifies ISO and EPC tags.

• Create a virtual representation of a given
  physical environment.
• Monitor existence and location of physical
  objects.
• Use non-intrusive devices like sensors and RFID
  readers instead of intrusive devices like camera.
  
• Useful to search, locate and inventory objects
  at home, hospitals, factory, stores and
  libraries.
• Inexpensive to deploy and use. Low power. Low
  maintenance.

MICA2DOT Crossbows Processor Radio Module

• Atmel Atmega 128L processor.
• Chipcon CC1000 radio 900MHz/433MHz.
• Atmel AT45DB041B 512kB memory.
• CR-2354 coin cell.

• Crossbows mica2dot processor radio module.
• Skyeteks M1-mini RFID reader.
• CR-2354 coin cells.
• Open source TinyOS software.

Basic Principle

• RFID readers are capable of identifying specific
  objects by reading tags attached to the objects.
• Sensors like photo detectors, pressure sensors,
  accelerometers etc detect the presence of objects
  and personnel.
• Sensors and RFID readers combined with tiny
  motes form a standalone system that can sense,
  process and communicate wirelessly.
• Low cost if produced in bulk.

Receiver Crossbows Data Acquisition Module

• Crossbows MIB510 serial port programmer.
• Crossbows Mica2 mote.
• Interfaces with the computer. via serial port.
• Communicates with RFID mote via radio to receive
  alerts.

Virtual Medicine Cabinet- A Prototype
RFID Mote Wings Labs RFID Mote

• Represents a real medicine cabinet in virtual
  space.
• Detects removal and re-shelving of objects in
  the cabinet.
• Shows locations of objects in the cabinet..
• Tracks how many time an object has been used.
• Uses non-intrusive RFID motes.

• Crossbows mica2dot processor radio module.
• Skyeteks M1-mini RFID reader.
• CR-2354 coin cells.
• Open source TinyOS software.
