Cart A Robust Glass-Breakage Detector Reference Design
(ACTIVE) TIDM-GBD-ROBUST
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
Description
This reference design implements a modified version of the hardware and software for the Simple Glass-Breakage Detector Reference Design. This modified version is more robust, with comparable current consumption values to the simple glass-breakage detector. The robust glass-breakage detector includes an extra thud detection stage before actual glass-breakage detection to avoid false triggering of the glass-breakage detector for sound events with signal spectrum similar to a glass-break sound.
Features
- Fully integrated, single-chip glass breakage detector
- Integrated Op-amps provide on-the-fly configurable filtering stages for signal detection and processing
- As low as 50µA average current consumption during monitoring operation
- Implements high power output horn driver stage capable of up to 106dB
- Addition of thud detection for better false trigger rejection
- This reference design is tested and includes firmware, hardware design files & documentation
- Hardware based on this design can also be ordered from Olimex.com
