  • Active shooter and environment detection
    Patent number: 9830932
    Abstract: A sensor device to detect an audio wave and determine whether the audio wave is a gunshot is provided. The sensor device may include microphone, analog-to-digital converter (ADC), microcontroller, and switch. The ADC may convert audio waves received from microphone into a digital signal. The microcontroller connected to the ADC may compare the digital signal of the audio waves with predetermined audio wave to determine whether the audio waves meet audio threshold parameters. The switch operatively connected to the microcontroller may transmit a trip signal to a predetermined emergency management and response system upon the microcontroller determining that the audio waves meet the audio threshold parameters. A gunshot detection system including the sensor device and a method of detecting a gunshot are also provided.
