Portal Monitor for Small, Moving Objects (27)
Problem: Provide a practical means for rapid, non-contact monitoring of individual honey bees entering/leaving a hive
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Controls & Measurements
PNNL Solution:
- Determined if small Radio-Frequency (RF) Tags (29) could meet operational needs
- Fit each bee with RF tag (30 mg ea)
- Located multiple antennas in the hive to sense bee identity & motion direction (in/out)
- Had hive ID, bee ID, transit direction, time, and date sent via rf modem link to central data collection/analysis system
- R&D 100 Award winner in 2001
- FLC Award winner in 2002
Capabilities Employed to Meet Client Needs: Radio-frequency (RF) field theory for antenna design and field propagation; information theory for evaluation of read/write distance effects on data transfer rates; analog and digital electronics design; prototype RF tag reader design, fabrication, and evaluation; lab testing; test planning and analysis; Visual Basic software interface; documentation of technical basis and results.
