Mosquito Detect Compass

Mosquito Detect Compass is a playful ultrasonic frequency explorer. Use your phone’s microphone to view high‑frequency peaks (8–23 kHz) and a compass‑style visualization to explore directionality.

Features
- Live ultrasonic peak detection with FFT
- Directional Search compass with bins and heading readout
- Simulated signal mode for demos
- Demo heading mode when the rotation‑vector sensor is unavailable

Notes
- For entertainment and demo purposes only.
- Results vary by device and environment and do not reliably indicate mosquito presence.
- Requires microphone permission; heading sensor is optional.
