This project presents the design and implementation of a real-time temperature and heart rate monitoring system using National Instruments (NI) myDAQ hardware and LabVIEW software. The primary goal is to develop a cost-effective, portable, and user-friendly biomedical monitoring solution suitable for educational use, preliminary diagnostics, or home healthcare applications. The system utilizes analog sensors, including an LM35 temperature sensor and a heart rate sensor, to acquire physiological signals from the human body. These signals are conditioned and digitized by the NI myDAQ, which acts as the interface between the sensors and the computer. LabVIEW, a graphical programming environment, is employed for real-time signal processing, analysis, and visualization. Key software features include live data plotting, threshold-based alerts, and data logging for future review. Experimental results confirm that the system reliably measures body temperature and heart rate with adequate accuracy for non-clinical environments. Its modular architecture supports future enhancements, such as wireless data transmission and cloud-based health monitoring. This project underscores the potential of integrating LabVIEW with myDAQ for rapid prototyping in biomedical instrumentation
