AudioMoth (Acoustic Recording Hardware)
Affordable acoustic event detection and analytics.
Acoustic events are often extremely important in biological systems, and edge computation (non-connected, inexpensive hardware with appropriate signal analysis algorithms) can easily identify events as diverse as rare species mating signals (calls at particular frequencies) or illegal human activity in restricted areas (like vehicles, guns, or chainsaws).
Once these acoustic signals are identified, appropriate notification events can be triggered, such as sending alerts to appropriate enforcement personnel by low-power, long-range radio (LoRa) or other protocols.
