4. HEART BEAT MONITOR
Wrist band for calculating heart beat
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.

5. 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.

6. Measurement of Heart rate
• Stethoscope ---
inaccurate
• Electrocardiogram –
costly
& not user friendly

8. What we have done? ? ?
• We , in this project are measuring the heart beat using
the pulse oximetry logic.
• The timer we have set for counting the
heart beat is 0s.
• There is a set point we can decide, after
0 s the heartbeat would be shown on
the LED.

9. COMPONENTS WE USED ? ? ?
1.Breadboard
2. 555 timer IC
3. 2 pcs 10k resistors
4. Single strand wires for the
connection in the breadboard.
5. 1uF ceramic disc capacitor
6. 2 LEDS
7.Voltage source of 12 volt.

11. HEARTPULSE TESTING USING LED
• Finger is illuminated by red light
being emitted by red led.
• When heart will expand then there
will be more blood in blood vessels
as a consequence more absorption
of red light will occur and lesser
amount of red light will fall on
555timer ic , decrease in resistance of ic
will be less and large current will
through ic .

14. 555 TIMER IC
555 Timer IC is a classic timer IC which can be used in many kinds
of timing related applications, check all the 555 Timer Circuit here.
This is an 8 pin IC. The pin diagram of the 555 timer IC is shown in
the below image.

15. BC337 NPN Transistor
Transistor BC337 is an NPN bipolar junction
transistor.
The transistor BC337 consists of 3 pins,
base, emitter, and collector as

16. WORKING OF MISSING PULSE DETECTOR CIRC
• The 555 IC receives generate the pulses in our
heart by the help of connecting wires, which is
formed using resistor R1 and capacitor C1. Values
of R1 and C1 determines the time period in
monostable mode. R1 is connected across the
capacitor C1. Input signal is directly connected to
the trigger pin of the timer IC 555 and also
connected to a single 10k base resistor
• The triggering of LEDs based on our heart
beats

17. APPLICATIONS :-
• 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
R A G H U E N G I N E E R I N G C O L L E G E E E E E D C M I N I
P R O J E C T 17

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

P R O J E C T 18

19. 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.
