0 likes193 views
This document describes a health monitoring system using sensors and a Raspberry Pi device connected to the internet. The system monitors a patient's heart rate and body temperature using heartbeat and temperature sensors connected to the Raspberry Pi. The Raspberry Pi acts as a server, collecting sensor data and sending it over the internet to a web server. Doctors and others can then monitor the patient's vital signs from anywhere using devices connected to the internet like smartphones and laptops. The system provides low-cost remote patient monitoring without expensive medical facilities.

Abstract - In the advancement of Internet technologies all
machineries are inter related. Using the technology
Improvement, we can make many things in high effective and
simple for human life. There are several places of Internet of
Things (IOT) is used. Such as smart environment, smart home,
smart city, smart parking, agriculturefieldsand medicalfields.
In medical field also, there are several process are used
internet. In this paper, monitor patient’s heart rate, body
temperature using Raspberry Pi. After connecting Internet to
the Raspberry Pi board it act as a server. Then the server is
automatically sends data to the web server .Then these
parameters are monitorusingwebpageanywhere intheworld
using laptops, smart phone etc.
Key Words: Health monitoring system, heart beat sensor,
temperature sensor, IOT.
1. INTRODUCTION ( Size 11 , cambria font)
The population in the world is increasing day by
day. This brings a need for more healthcare options. To
developed healthcare technologies and facilities. The
proportion of senior citizens is increased in the society.
These senior citizens which requires proper medical care
than the rest of the population. So the monitoring and
recording of Physiological parametersofpatientsoutsidethe
clinical environment is becoming increasingly important in
order to take care of senior citizens. Today the networking
technologies are very much developed. So that the
communication or connection between the people,
multimedia and services have been greatly changed.
Wireless communications technologies has greatly affected
on the peoples lifestyle.
The “Internet of things” - IOT is a concept and mode
consisting of sensors, actuators, and development boards
interacting with each other connected over the internet
without any human intervention resulting into a more
intelligent system. In simple words, IOT refers to a network
of objects all connected to the internet at the same time. The
main principle of Internet of things (IOT) is that the
objects/things i.e. sensor nodes identify, sense, process and
communicate with each other [1]. IOT has a substantial
influence in healthcare domain. Still, there are so many
people who do not have accesstoqualityhealthcareservices,
thus remote patient monitoring becomes a need. Presently
Healthcare system is shattered with the lack of
communication between the patients and the doctors. Thus
to address this problem information technology becomes a
need. Healthcare services can be improved a lot with IoT-
enabled healthcare devices. By applying IOT concepts in
healthcare, there is a great possibility of virtually saving the
lives. E-health solutions based on IOT should provide worth
information about health to the patients and the doctorscan
make better decisions irrespective of their patient’slocation
[2]. IOT has already brought changes in various domains of
health care like intelligent healthcare tools and devices,
diagnostics and monitoring of patients, data storage,
transfer, and collaborations.
2. LITERATURE SURVEY
The study described in [1] monitors the health data
using the e-health sensor platform. The architecture has
been divided into 3 modules whicharesensingmodule,main
module and the interaction module using cloud to store the
data to remotely monitor the patient’s health.
In the proposed system described in [2], sensors
such as glucometer, airflow and accelerometer have been
used. Their main focus was to provide reasonable cost. As
described, medical sensors are attached to the body which
transmits the data through cloud using zigbee.
Another study of “real time wireless health
monitoring app using mobile devices’’ is a smart phone
based system which monitors the health parameters. The
biggest drawback of this system is that only health care
professionals can monitor and advice their patients about
the health concerning issues if any as proposed in [3].
3. SYSTEM ARCHITECTURE
The design part consists of mainly two sections:-
• Hardware architecture
• Software architecture](https://image.slidesharecdn.com/irjet-v6i4194-190621064330/85/IRJET-Design-and-Implementation-of-IOT-Based-Health-Monitoring-System-Using-Raspberry-PI-1-320.jpg)

communication(M2M). Unlike HTTP protocol which uses
request/response architecture, MQTT protocol follows
publish/subscribe architecture. It provides great flexibility
to the clients to connect as a publisher, subscriber or both.
By using this protocol, the user gets connected to MQTT
broker which is solely responsible for all themessagesbeing
transmitted and received.
4. METHODOLOGY
In this paper we have temperature, heart beat reading
results are monitored. These sensors signal are send to the
Raspberry Pi via ADC8080 because signals are in analog
form. To convert into digital form and send to Raspberry Pi.
Raspberry pi is linux based operating system worksassmall
pc processor system. Hear patients body temperature and
heart beat is measured usingrespectivesensorsanditcan be
monitored in the monitor screen of computer using
Raspberry pi as well as monitoring through anywhere inthe
world using internet source.

6. CONCLUSION
In this paper, we designed system gives minimum
complexity and very portable for healthcareobservingof the
patient. Furthermore, it disregards of the need of usage of
costly facilities. The specialist or the doctorcanreadilyget to
the patient’s information at any place with the help of
internet services. The proposed system used sensors
platform integrated with Raspberry pi board. Three sensors
have been utilized in this project and which temperature
sensor, heart beat sensor. All the patient's vital signs sent
remotely and displayed via system website.

The Raspberry Pi 3 Model B+ maintains the same mechanical footprint as both the Raspberry Pi 2 Model B and the Raspberry Pi 3 Model B. Fig 1: Raspberry pi 3 model B+ 3.1.2 Heartbeat sensor The heartbeat sensor is based on the principle of photoplethysmography. The blood volume changesthrough any organ of the body due to which the light intensity also changes through thevascularregion/organ. The rateofheart pulses decide the rate of flow of blood volumeandsincelight is absorbed by blood, the heart beat pulses are equivalent to signal pulses. The timing associated with the pulses is more important in the case where the pulse rate is to be monitored. Working of a Heartbeat Sensor: The heartbeat sensor consists of an Infrared LED and a photodiode(lightdetecting resistor ) to detect the pulse of the finger. On one side infrared LED is present whereas on the other side photodiode is present. When the light source illuminatesthe tissue, the reflected rays are being captured by the Photodiode . The output of the detector is an electrical signal which basically gives the number of pulses counted by the sensor. This pulse rate sensor is shown in fig. 2 has the following features –LED for the heartbeat indication, Digital output, Compact in size with the operating voltage of +5 V DC. Fig 2: Heartbeat sensor 3.1.3. Temperature sensor LM35 is a precision IC temperature sensor with its output proportional to the temperature (in oC).Thesensorcircuitry is sealed and therefore it is not subjected to oxidation and other processes. With LM35, temperature can be measured more accurately than with a thermistor. It also possess low self heating and does not cause more than 0.1 oC temperature rise in still air. The operating temperature range is from -55°C to 150°C. The output voltage varies by 10mV in response to every oC rise/fall in ambient temperature, i.e., its scale factor is 0.01V/oC.fig 3 show the typical view of temperature sensor. Fig 3: Temperature sensor 3.2 SOFTWARE ARCHITECTURE It includes MQTT protocol, 3.2.1MQTT protocol MQTT (Message Queuing Telemetry Transport) is a low bandwidth, a lightweight protocol which was developed in 1999 for connecting different devices and applications together especially for the machine to machine
