Open-source acoustic drone detection. It hears the propellers, not the radio, so it works against fibre-optic FPV aircraft that emit no signal at all.

About the project

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.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
