What? Widlife monitoring system – Use wireless sensor network to gather data about wildlife behavior and patterns

Why? Wild life research  Reduces cost  Better results  Less risky Environmental Impact studies  Development projects  Construction

How? Movement/Motion Take photographs Temperature Humidity Light Geological shocks, GPS, Wind Perform simple data manipulation and interpretation.

Photo Courtesy of Google Maps Temp = 70 0 F Humidity = 26% Light level = 87% Movement = TRUE Photo

Key considerations Size and Cost  High number of sensors Durability  Exposed to elements 24 hours a day Power consumption:  Replacement of batteries not viable  Battery life >6 months
