This work presents the design and construction of a multiparametric biomedical signal monitoring system intended for the acquisition, visualization, and analysis of physiological variables. The proposed system integrates three main components: a sensing module, a data acquisition system, and a graphical user interface. The sensing module was designed to acquire electrocardiographic (ECG), phonocardiographic (PCG), respiratory, and body temperature signals using noninvasive sensors and appropriate signal conditioning stages. The acquired signals are digitized through an Arduino Uno–based acquisition system and transmitted to a computer for processing and visualization. A graphical user interface developed in LabVIEW enables real-time monitoring, waveform display, and parameter supervision in a user-friendly environment. The prototype also incorporates electrical isolation and patient safety considerations according to biomedical equipment standards. Experimental results demonstrate that the system is capable of reliably acquiring and displaying the physiological signals under study. The developed prototype represents a low-cost and portable alternative for biomedical monitoring applications, particularly in clinical and home-care environments.
