A heart rate monitor is a personal monitoring device which allows one to measure his or her heart rate in real time or record the heart rate for later study. It is largely used by performers of various types of physical exercise

2. HEART BEAT MONITOR
• A heart rate monitor is a
personal monitoring
device which allows one
to measure his or her
heart rate in real time or
record the heart rate for
later study. It is largely
used by performers of
various types of physical
exercise.
• Widely used in hospitals
for checking the health
of patient(s)

heart beat

3. HEART BEAT DETECTOR
• Taking your pulse is as simple as holding a finger to
your neck or wrist and timing the beats with your
watch.
• But if you want to record the data or use it to trigger
events, you need to turn that mechanical pulsing
action into an electrical signal.
• This sensor fits over a fingertip and uses the amount
of infrared light reflected by the blood circulating
inside to do just that.

4. Why Monitoring……?
• More than 2 million people are at high risk of having
heart attack.
• It would be helpful if there was a way for these
people to monitor their heart.
• So we have a problem. That is the way our project
focuses on how we can utilize this problem and find a
solution.

• Stethoscope ---
inaccurate
• Electrocardiogram –
costly
& not user friendly

7. What is a microcontroller and why
microcontroller are not a microprocessor?
7
• A microcontroller is a single-chip microcomputer which
contains RAM, ROM, CPU, I/O ports, ADC and other
peripherals.
• It has fixed amount of RAM, ROM, I/O ports.
• It is also called embedded microcontroller because it is
designed for embedded systems performing specific tasks
only.
• Microprocessor only has CPU, ALU, stack pointer, program
counter and other registers, clock timing circuit.
• Microprocessor does not have RAM, ROM and I/O ports
• It requires large space and it’s cost is higher as compared
to microcontroller.

11. PROCEDURE :-

1. When we will give the power supply to the Arduino Nano which is
connected with the heart sensor.
2. Now we will put our finger on the heart sensor and Infrared light is
absorbed by the blood, a sensor measures the amount that the
infrared light is darkened by. If it is significantly darker, due the
pulse causing a temporary increase in the amount of blood that is
travelling through the measured area, that is counted as a heart
pulse.
3. Now since the heart sensor is giving that analog value so it ill be
converted into the digital value using ADC pins of the Nano board.
4. After calculating the digital value of the heart beat it will display
on to the LCD with the number of beats.
5. The normal person heart beat varies to 60 to 80.
6. We keep the conditions if the adults heartbeat is lower than 55
and above than 85 than the buzzer will sound and give the
indication of Heart Attack.

PIN CONFIGURATION SCHEMATIC LOOK

15. HOW HEART SENSOR SENSE THE HEART BEAT?
 The sensor itself consists of
an infrared emitter and
detector mounted side-by-
side and pressed closely
against the skin.
 When the heart pumps, blood
pressure rises sharply, and so
does the amount of infrared
light from the emitter that
gets reflected back to the
detector.

16. HEART BEAT SENSOR WORKING
 The detector passes more current
when it receives more light,
which in turn causes a voltage
drop to enter the amplifier
circuitry.
 This design uses two consecutive
operational amplifiers (“op-
amps”) to establish a steady
baseline for the signal, emphasize
the peaks, and filter out noise.
 Both op-amps are contained in a
single integrated circuit (IC or
“chip”),

21. Applications :-
21
• Have become a widely used training aid for a
variety of sports.
• Hospitals / Dispensaries
• Better and accurate method of measuring heart
beat.
• At homes
• A set point can help in determining whether a
person is healthy or not checking his/her heart
beat and comparing with set point.

22. LIMITATIONS:-
22
• In-accurate method of calculating
heartbeat.
• Logic used in very simple. Therefore,
results may vary as for a sophisticated
instrument for the same purpose

23. FUTURE SCOPE:-
• EEG, ECG and other health parameters can also be
monitored.
• Continuous monitoring and future diagnosis can be
performed via the same system (TELEMEDICINE).
• More than a single patient at different places can be
monitored using single system.
