Description
This application report describes a simple glass breakage detector using the MSP430F2274 ultra-low-power microcontroller (MCU). The algorithm is based on the spectral analysis of a typical glass breakage signal. The input signal spectrum limited to a frequency of 20 kHz is processed for a valid glass breakage. Various signal characteristics such as peak content number of zero crossings and fre
