Introduction
The project Heart Beat Monitor is a very useful project for medical field. This can be used to monitor the heartbeats in digital display format. The heart beat information available in digital format is easy to understand. In our heartbeat monitor project we have used two electrodes to sense the blood pumping done by heart which are proportional to heartbeats. The sensing electrode sense the blood pumping cycles and send the signal to current amplifier. We are using three stages of amplifiers to amplify weak signals sensed by sensing electrodes. The amplified signals are processes to extract the cycles of blood through our body. The average value of sensed cycles of blood pumps are displayed per minute interval. We have used microcontroller AT89S51 to process the sensed signal from sensor and displayed on 16x2 LCD display.
