# agamrossen/VolAnti

> Open-source acoustic drone detection: listens for propeller harmonics, not radio, so it works against fibre-optic FPV drones that emit no signal. ESP32-S3 device with four microphones, e-paper screen and LoRa for alerts.

## Useful for

- Build a low-cost acoustic drone detector on ESP32-S3 for local alerting.
- Deploy a network of LoRa-connected units for early warning of approaching drones.
- Test the detector on a sound field simulator before building the hardware.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
