Portable Passive Acoustic UAV Detection and Recognition Early Warning Device

1.Main Functions

1.Detects surrounding UAVs by capturing acoustic signal characteristics via a 4- channel MEMS sensor.

2.The detection radius is about 100m - 300m (specifically subject to the environmental noise).

3.Provides accurate audible, visual, and vibration alerts, and identifies common civilian UAV types including quadcopters, fixed- wing, DIY, and fiber- optic FPV drones.

4.The device supports a harsh working environment with an operating temperature range of -20°C to 55°C.

5.The device adopts a lithium battery with a working time of no less than 6 hours, and the working time of the low-temperature battery is no less than 3 hours.
