Heart Rate Monitor using 8051 – is a very useful health/medical application project kit. This project kit is a model of Heart Rate Measuring devices we see in hospitals, especially inside ICU (Intensive Care Units). Heart Rate Monitor project kit is designed on the principle of Photoplethysmography (which is the process of optically estimating volumetric measurement of an organ). The device senses the heart rate from the finger tip using IR reflection method and displays it on a 16×2 LCD display in beats per minute. This project kit is very unique and is ideal for students taking Bio Medical courses like Bio Medical Engineering.
