HEART RATE MONITORING SYSTEM USING FINGER TIP
THROUGH ARDUINO AND PROCESSING SOFTWARE

INTRODUCTION
• A heart rate monitor is a personal monitoring device that allows a subject to measure their heart
rate in real-time. Early models consisted of a monitoring box with a set of electrode leads that
attached to the chest. The heart rate of a healthy adult at rest is around 72 beats per minute
(bpm) & Babies at around 120 bpm, while older children have heart rates at around 90 bpm.
• The heart rate rises gradually during exercises and returns slowly to the rest value after exercise.
The rate when the pulse returns to normal is an indication of the fitness of the person. Lower
than normal heart rates are usually an indication of a condition known as bradycardia, while
higher is known as tachycardia. Heart rate is simply measured by placing the thumb over the
subject’s arterial pulsation, and feeling, timing and counting the pulses usually in a 30 second
period. Heart rate (bpm) of the subject is then found by multiplying the obtained number by 2.
This method although simple, is not accurate and can give errors when the rate is high. More
sophisticated methods to measure the heart rate utilize electronic techniques. Electro-
cardiogram (ECG) is one of frequently used method for measuring the heart rate. But it is an
expensive device. Low-cost devices in the form of wrist watches are also available for the
instantaneous measurement of the heart rate. Such devices can give accurate measurements
but their cost is usually in excess of several hundred dollars, making them uneconomical. So this
heart rate monitor with a temperature sensor is definitely a useful instrument in knowing the
pulse and the temperature of the subject or the patient.

MOTIVATION
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 focus on how we can utilize this
problem and find a solution.

MCP602 Opamp
• The MCP602 dual operational amplifier (op amp) has a gain
bandwidth product of 2.8 MHz with low typical operating
current of 230 uA and an offset voltage that is less than 2 mV.
• The MCP602 uses Microchip’s advanced CMOS technology,
which provides low bias current, high-speed operation, high
open-loop gain and rail-to-rail output swing. It operates with a
single supply voltage that can be as low as 2.7V, while drawing
less than 325 of quiescent current per amplifier.
• It is available in standard 8-lead PDIP, SOIC and TSSOP packages.
• This amplifier is ideal for industrial process control, low-power
battery- operated devices, portable equipment, data acquisition
equipment, test equipment and low-end audio applications.

ARDUINO Hardware
The Arduino Uno can be powered via the USB
connection or with an external power supply. The power
source is selected automatically [4]. The Arduino Uno is a
microcontroller board based on the ATmega328, which External
(non-USB) power can come either from an AC-to-DC adapter
(wall-wart) or battery. The adapter can be connected by
plugging a 2.1mm centre-positive plug into the board's power
jack. Leads from a battery can be inserted in the Gnd and Vin
pin headers of the POWER connector.

The ATmega328 is a single-chip microcontroller created by Atmel in
the megaAVR family.
The Atmel 8-bit AVR RISC-based microcontroller combines
32 kB ISP flash memory with read-while-write capabilities,
1 kB EEPROM, 2 kB SRAM, 23 general purpose I/O lines, 32 general
purpose working registers, three flexible timer/counters with compare

programmable watchdog timer with internal oscillator, and five
software selectable power saving modes. The device operates between
1.8-5.5 volts. The device achieves throughput approaching 1 MIPS per
MHz.

Working of IR sensor
An IR sensor can measure the heat of an object as well as
detects the motion. These types of sensors measures
only infrared radiation, rather than emitting it that is called as a
passive IR sensor. Usually in the infrared spectrum, all the
objects radiate some form of thermal radiations.

RESULTS AND CONCLUSION
analogue signals of heart rate acquired by the sensor through finger.
The system was used to measure the heartbeat rate of a number of
male and female volunteers. The results of the developed system
compared with a conventional measuring method. These results
show acceptable range compare to manual measurement. Another
experiment was conducted where we measured the beat rate of
two male volunteers at rest. The volunteers then performed some
exercise (jogging) for five minutes and their heartbeat rate was
subsequently measured. The readings of the device were compared
against the manual measurement. The manual measuring data were
taken by counting the pulse from the wrist. Overall, the results are
in an acceptable agreement with the actual readings.

Conclusion

time processing heart rate counting system has been presented. The
device is portable, durable, flexible, reliable and cost effective. Also, it is
efficient, easily estimable data and easy-to-use for the end user.
Experimental results have shown acceptable range with actual
heartbeat rates. Finally, this handheld system has proven to be an
excellent heart rate counting system for the end user.
