Glass break sensors play a critical role in crime prevention by adding an extra line of security and protection to homes and buildings. These sensors usually use a microphone which monitors any noise or vibrations coming from glass windows to detect if a pane of glass is shattered or broken.

This glass break detector solution uses a microphone to detect when the glass is broken; active filtering for the microphone is implemented using the microcontroller's on-chip low power op-amp. Additionally, the solution reduces costs while achieving extended operation on battery power.

Circuit diagrams, parts lists and sample programs are available.
