TRANSCRIPT
Mote Network Operational Scenario
• Motes enclosure includes a transparent window
• Motes have 4 enclosure-internal and 4 external sensors
• Motes acquire 8 data values every 5 minutes– Temperature oC: Two external, one internal– Relative humidity RH: Two external, one internal– Photosynthetically Active Radiation (PAR): One internal– Total Solar Radiation (TSR): One internal
• Periodically data is recovered to a Gateway Mote– Once every 12 hours– Gateway leads to a computer where data is stored in a database.
• Motes otherwise hibernate to extend field operation lifetime
