The Main Idea

Provides the firefighting community the ability to safely, easily measure, view fire & weather conditions over a wide

range of locations and elevations within forest fires. The designed system uses integrated a multi hop sensor

network to provide environmental data integrated web-enabled surveillance cameras to provide visual data.

Fire Wx Net

consisted of 5 long range links, 3 sensor networks consisting of a total of 13 nodes, 5 wireless access points, and 2 web cameras.

The Main Achievements

built a system that successfully presented an elevational gradient of environmental conditions in wild land fire environments. This previously unattainable information will help fire behavior analysts make better predictions about fire conditions and create a ’more aware’ environment in the fire community, which will in turn help make fighting forest fires safer in the future.by using wireless technology &sensor networks

The Backhaul link set up on Boulder Peak. To the near side is an Access5830 with a directional antenna. On the far side is a M900S connected to a Yagi antenna. Below are two of the solar panels we used to provide power.
