An Efficient Microcontroller Based Heart Rate Monitoring

Abstract

The main aim of this project is to monitor the heartrate using fingertip sensor. The device uses the optical technology to detect the flow of blood through the finger and offers the advantage of portability over tape-based recording systems.The main components used in this project are Microcontroller, power supply unit, heart rate sensor and LCD to Display the heart rate.In this project the heart rate sensor senses the heart pulse and gives the values to the microcontroller and which is further processed by microcontroller to display the count of the heart pulses on the LCD.In medical termminology, the technique used here for sensing heart rate is called photoplethysmography.
