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

System Block Diagram Transceiver Solution XBee-PRO DigiMesh 900 Transmit Power 50mW 6 miles (w/ High gain antenna) LOS Range Built in mesh Cost

Pros Cons Yes $45.00

Build in mesh protocol Scalable and interoperable w/ devices from different vendors UHF can penetrate dense forestry Self-healing and discovery for stability Highest price XBee-PRO DigiMesh 900 Transceiver Antenna Solution

7" half wave, bulkhead mount, RPSMA connector Microcontroller Solution 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 Message length Throughput Transmition time

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 Thank You Any Questions?
