Acoustic Sensor

A wireless, battery-powered sensor system for detecting drones, gunshots and explosions through sound analysis. Operates independently of visual line-of-sight – at night, in fog, around obstacles.

Key Capabilities

• 

  Drone detection via motor acoustic signature (2–8 kHz band)

• 

  Gunshot detection (impulsive onset < 1 ms)

• 

  Explosion detection

• 

  Edge AI inference directly on the sensor (TensorFlow Lite) – minimal data throughput

• 

  LoRaWAN 868 MHz wireless communication (range 1–10 km depending on terrain)

• 

  IP65 rating, battery life 35–45 hours (swap < 2 min)
