Continuous heart rate and body temperature monitoring system using arduino uno and android device
The document presents a continuous heart rate and body temperature monitoring system that utilizes Arduino and an Android device, aimed at providing doctors with real-time patient data remotely. The system employs an optical sensor for heart rate measurement and an LM35 sensor for body temperature, with data transmitted via Bluetooth to an Android application. Future enhancements include data storage, centralized patient health monitoring, and implementation within IoT frameworks.

Motivation
Heart rateindicates the soundness of our heart
Heart rate helps assessing the condition of cardiovascular system
It is not possible for a doctor to observe a patient’s heart rate per minute and
body temperature all the time
Again a doctor far way from the patient need to know heartrate and body
temperature for initial treatment
An embedded system which can measure the heart rate and body
temperature and store the data for the doctor to know the condition of the
patient can help for this purpose
Objectives
The major objectivesof our developed system are listed below:
To measure heart rate
To measure body temperature
Continuously display the result in Android device
To observe the patient’s health condition continuously
TCRT5000 Optical SensorFor
The sensor used in this system is
TCRT5000 which is a reflective
optical sensor. It consists of an
infrared LED that transmits an IR
signal through the fingertip of the
subject, a part of which is reflected by
the blood cells. The reflected signal is
detected by a photo diode sensor. By
sensing the change in blood volume
in a finger artery while the heart is
pumping the blood.

Processing Data ThroughArduino UNO
Body Temperature Calculation
Voltage to Temperature conversion:
Temperature in degree Celsius,
Temp = Output voltage * 0.48828125
Celsius degree to Fahrenheit degree conversion :
tempf=(Temp*1.8)+32
Heart Rate Calculation:
sum = 𝒊=𝟏
𝟑𝟎
FreqMeasure.read()
frequency = F_CPU / (sum / 30)
BPM=frequency * 60

Transferring Arduino UNOProcessed Data
to Android Device via Bluetooth
The HC-05 module
communicates with the
Arduino via a serial
connection and transfers
data to the connected
Android device.
HC-05 Bluetooth Module
Heartmate Android Application
Thisis the simple Android
application:
Runs on Android API 17
and more
Shows heart beat rate
Shows body temperature
Future Work
Storepatient’s heart rate and body temperature in Android
device provided SQLite Database system
Implement continuous patient health care monitoring
system through centralized server in medical
Implement the system at low cost
Implement remote health monitoring system through
“Internet of things (IoT)”
