Glass break detector

Block diagram

Overview

Our integrated circuits and reference designs help you create a glass break detector design that maintains long battery life while continuously listening for the sound of shattered glass.

Design requirements

Glass break detectors often require:

  • Amplification and filtering of both low-frequency (< 300 Hz) and subsequent high-frequency (> 9kHz) glass break sounds.
  • Reduced maintenance through battery-powered designs with long battery life.
  • Ultra-low-power wireless communication with 2.4-GHz and Sub-1-GHz networks.
