What?

• Widlife monitoring system– Use wireless sensor network to gather data about

wildlife behavior and patterns

Why?

• Wild life researchReduces costBetter resultsLess risky

• Environmental Impact studiesDevelopment projectsConstruction

How?• Movement/Motion

• Take photographs

• Temperature

• Humidity

• Light

• Geological shocks, GPS, Wind

• Perform simple data manipulation and interpretation.

Temp = 700FHumidity = 26%Light level = 87%

Movement = TRUEPhoto

Key considerations• Size and Cost

High number of sensors

• DurabilityExposed to elements 24

hours a day

• Power consumption:Replacement of batteries

not viableBattery life >6 months

Milestones

First Milestone• Initial prototype

– Motherboard– Sensor unit– Initial human interface– Wireless communication

Second Milestone• Final network

– Testing and debugging – Fully functional sensor units

and motherboard

Mid Range Goals

• Three sensor boards, one mother board– Fully functional wireless communication• Ability to send images, sensor data, and receive

instructions from mother board

• Human Interface– Data processing and display with MatLab– Ability for user to modify behavior of sensor

network

High Range Goals

• Sensors packaged in fully functional, weather proof unit.

• Have data gathered by network uploaded onto website

• Integration of additional sensors– GPS, wind, geological shocks

• Environment model built in lab for demo day

Risks and contingency plan

• Testing expensive components• Unfamiliar Technology :

Programming the camera

• Schedule uncertainty• Ability to transmit data• Unclear photos at night• Testing in lab and real life
