Ridgeline Meteorological Sensor Network Stephen Copeland, Xau Moua, Joseph Lane Advisors: Dr. Manimaran Govindarasu, Dr.Venkataramana Ajjarapu
Problem Statement • Small scout towers capable of wirelessly transmitting measurements to large MET towers. • Wireless communication via radio transceivers on scout tower and MET tower. • Built-in mesh networking protocol
Transceiver Solution XBee-PRO DigiMesh 900 Transceiver
Antenna Solution • 7" half wave, bulkhead mount, RPSMA connector
Testing • Range • various locations on campus • Power consumption • Use of LabView and multi meters to measure current and voltage levels • Microcontroller • Basic data communication • Message integrity • Throughput
Testing (cont.) • Self Healing • Selected modules turned off during transmission • Security • Channel hopping, Encryption, • Latency • Receiving rate vs. data size • Casing • Shock, vibration, realistic impact, and submersion in water.
Current Status • Transceivers and antennas received • Documentation Finalized • Proposal for acquisition of used sensors • Initial communication testing • More unit and system level testing is required
