Embedded Acquisition System for the Lung Sound Signal Based on STM32 Microcontroller

Abstract:

The accurate detection of lung sounds is the premise and infrastructure to achieve non-invasive diagnosis of cardiovascular disease, and the disease noninvasive diagnostic methods based on cardiovascular lung sounds have non-invasive, fast, convenient, and economic characteristics. According to this, the embedded acquisition system for lung sound signals is designed based on the STM32 microcontroller, Stethoscope and electrets microphone is adopted as the lung sound signal acquisition module. The experiment is done based on this system, and the result shows that this designed system working properly, and reliable design.
