iot based patient health monitoring system using arduino.pdf

In the realm of modern healthcare, continuous and remote monitoring of patients' health is becoming increasingly essential. Traditional methods of health monitoring often require frequent visits to healthcare facilities, which can be inconvenient and costly. An IoT-based patient health monitoring system using Arduino offers a solution to this challenge by enabling real-time, remote tracking of vital health parameters.

INTRODUCTION
A REMOTE HEALTH MONITORING SYSTEM IS AN ADD-ON
TO HOSPITAL'S MEDICAL SYSTEM THAT ALLOWS
DOCTORS TO MONITOR A PATIENT'S VITAL FUNCTIONS
FROM AFAR.
NOW IN ADVANCED TECHNOLOGIES A GREATER NO. OF
SENSORS AND MICROCONTROLLERS ARE PRESENT
WHICH IS COST WISE LOW, THE SPEED OF OPERATION IS
HIGH AND POWER CONSUMPTION IS LOW.
THE PROCESS HAS LED TO REMOTE MONITORING OF
IMPORTANT LIFE SIGNS OF PATIENTS, PARTICULARLY THE
ELDERLY AND PERSONS IN QUARANTINE WHO ARE ILL.
A HOSPITAL'S MEDICAL SYSTEM IS SUPPLEMENTED WITH
REMOTE HEALTH MONITORING SYSTEM THAT AALOWS
FOR REMOTE MONITORING OF CRUCIAL BODY STATUS OF
A PATIENT.

4. SYSTEM BLOCK DIAGRAM
The proposed IoT-based health monitoring system was developed
using Arduino microcontroller which is the brainof the project.
IoT Based health care monitoring is mainly focused for the doctors and
patients..This Automated system is to provide quick health monitoring.
The Temperature Sensor and Pulse Sensor is connected to provide the
temperature and pulse rate of patients through the LCD Display.The
Patient informations are Shared with the patient attender and also doctors.
Sensor is a device that converts signals from one energy
domain to electrical domain. IoT based patient health
monitoring has 2 sensors. The first one is a temperature
sensor and the second is the Heartbeat sensor.

5. An Arduino digital temperature sensor measures the patient's body
temperature. One temperature sensor is connected to Arduino to measure
room temprature so that we can adjust the room temperature according to
our health and body temperature .
A temperature sensor is an electronic device that measures the temperature
of its environment and converts the input data into electronic data to record,
monitor, or signal temperature changes.
Arduino collects the real-time health data from a pulse sensor
that measures heart rate in minutes or BPM (beats per minutes).
Heartbeat Sensor is an electronic device that is used to measure
the heart rate i.e. speed of the heartbeat.

6. CIRCUIT DIAGRAM
The circuit diagram of IoT based Patient Health Monitoring system is
shown in the figure :
THE PATIENT HEALTH MONITORING SYSTEM CONSIST OF THE
FOLLOWING:
ARDUINO UNO BOARD: It is one of the most popular development boards used for
experimental purposes and serves as an Internet of Things (IoT) link.
PULSE SENSOR : Pulse sensor that measures heart rate in minutes or BPM (beats per
minute).
LM35 TEMP. SENSOR : To measure room temperature so that we can adjust the room
temperature as per health and body temperature.
LCD DISPLAY: LCD is a flat optical display device which uses liquid crystals' light-modulating
properties combined with polarizers.
LED : Light Emitting Diode to show red,green,blue on different conditions.
ESP8266 : The module will work individually as an Associated Objective access point (can display hotspot
and as a channel (can connect to Wi-Fi), where it will simply download information and transfer it to the
web creating a Web of things as simple as accessibility.
OTHERS: Other components like resistor,breadboard,connecting wires etc.

14. The major goal of the suggested system is to improve the healthcare
monitoring system. No one has time to constantly look after others in
the current scenario. As a result, all levels of employees require a
continual monitoring system.
The current communication technology concepts were used to create
this new device. IoT is important in a variety of fields. The suggested
system's major goal is to improve the quality of healthcare monitoring.
RESULT AND DISCUSSION
Most healthcare businesses have used the Internet of Things (IoT)
concept to collect continuous real-time data. Continuous monitoring is
required in the health-care system. Temperature and pulse sensors are
used to build this proposed device. The real-time human body
informations are collected using these sensors.

15. The main aim of the proposed system is developing the healthcare
monitoring system in better way. This system is very useful for elderly
people, physically challenged people and covid affected people in home or
hospitals.
Compare with other monitoring devices the proposed device provides a
better result and easy to use.
CONCLUSION
The proposed patient health monitoring system can be used extensively
in an emergency conditions as they can be monitored daily, recorded and
stored as a database. In the future Iot device can be integrated with
computer computing so that the database can be shared across intensive
care and treatment hospitals.
