Overview

Early Wildfire Alert Network (EWAN)

The “Early Wildfire Alert Network” (EWAN) consists of thousands of humidity and temperature sensor nodes distributed over remote forestland. Each node contains a wireless transceiver that enables EWAN to instantly communicate the onset of wildfires as well as constantly monitor forest conditions for accurate, day-to-day, fire hazard prediction.

While most of the technology behind EWAN is inexpensive and has been available off-the-shelf for several years, the necessity of constantly replacing batteries at thousands of hard-to-reach locations has kept “smart dust” or mesh-network solutions to forestland monitoring from being implemented in the past.

Voltree Power solved the problem of battery replacement by developing a small and inexpensive electricity generation system that harvests metabolic energy from the trees themselves and converts it to useable electricity.

This “bioenergy converter” has been integrated into a power module that does not depend on wind, light, heat gradients or mechanical movement and is environmentally benign to produce and run. It is weather resistant, completely quiet, leaves no heat signature and is about the size of a small pack of gum. It parasitically harvests metabolic energy from any large plant without harming it. The useful lifetime of the device is only limited by the lifetime of the host.
