The goal of the project is to create a MESH Network of Infrasonic Wildfire Sensors.
Contents
Problem Definition[edit]
Wildfires ravage through the forests and destroy ecosystems and economies, yet still, our best means of detection is by seeing and smelling smoke. The ability to provide a signal to firefighting services when the fire is still small could save countless homes and wilderness areas. In order to modernize this detection process, we propose a device that uses infrasonic detection and signal processing to detect wildfires. Our aim is to set up a mesh network of smart nodes and dumb nodes that can detect infrasound waves (0 – 20 Hz) and communicate this information wirelessly. This technology has the potential to drastically improve our ability to mitigate wildfires by allowing us to detect the problem sooner.
Background[edit]
- Wildfires produce a sound signature in the infrasonic range.
- Detecting sound in that frequency indicates the presence of a wildfire.
- Cheap communication electronics has made it possible to create a distributed sensing network.
- Affordable and resilient sensors for infrasound are now a possibility.
Deliverables[edit]
3 sensor devices, capable of detecting infrasonic sound waves and networking with each other and the internet.
Specifications[edit]
- Detect infrasonic sound waves.
- Creates a mesh network of similar devices to transmit fire status.
- Has a rugged enclosure capable of surviving drops and impacts, as well as surviving the elements.
