In recent technological innovations in the field of disease prevention and maintenance of patient health have enabled the evolution of fields such as monitoring systems. Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. It can be measured either by the ECG waveform or by sensing the pulse - the rhythmic expansion and contraction of an artery as blood is forced through it by the regular contractions of the heart. The pulse can be felt from those areas where the artery is close to the skin. We proposed a system that monitors the heart beat of a person using sensor and embedded system and display it on the LCD. We also included an alarm system which alerts the person in emergency situation.

 Hardware Requirement

1.     Arduino Nano Microcontroller

2.     Power Supply (5V DC power adapter)

3.     Heart Beat Sensor

4.     16x2 LCD Display

5.     Buzzer

6.     Jumper Wires

7.     Bread Board (170 points)

The block Diagram of the heart beat rate monitoring and alerting system is shown above. It consists of three modules such as Heart beat sensor, Microcontroller section, Alarm and LCD display. Heart beat sensor has a direct contact with the human finger to detect the heart beat of the human. The output of the sensor is given to the microcontroller section which reads the heart beat value, If abnormal heartbeat is detected, then it activates the alarm module and also heart beat value will be continuously displayed in LCD.
