This application report describes a simple glass breakage detector using the MSP430F2274 ultralow-power MCU. The algorithm is based on the spectral analysis of a typical glass breakage signal. The input signal spectrum, limited to a frequency of 20kHz, is processed for a valid glass breakage. Various signal characteristics such as peak content, number of zero crossings, and frequency composition are analyzed. Real-time signal processing is achieved by implementing and using a low-order bireciprocal lattice wave digital filter (LWDF). A glass breakage alert is indicated by an onboard buzzer and an LED. The entire setup is designed to operate at low power, allowing long battery life.
