Realize glass breakage detection through air pressure change detection and full-frequency sound detection: - The solution is accurate, safe and contact-free installation. - One-to-many glass breakage detection is not easily disturbed by environmental sounds. - Can be widely used in commercial and home security. The main control part of the solution uses Microchip's ATSAMG55 series MCU, which is connected to Infineon's digital silicon microphone IM69D130 through its internal integrated PDM interface to complete sound detection, and air pressure detection is completed through Infineon's DPS310 chip.
