Abstract—In this paper we designed to monitor the
temperature, humidity and pulse rate of the patientusingIOT.
Through this we can easily send the real time information to
many users to and also we can send alter message to doctor
old person the pulse rate range is between 54 to91bpm.The
over internet in critical conditions and the buzzer is turn on in
order to alert the caretaker who are available in the premises.
Now a day’s death rate is increased in India because of heart
attacks and reason behind this cause is that, the patients are
not getting the proper check-up during the period of time. In
order to provide the proper check-up for patient we need to
monitor the health of the patients continuously. In the
traditional approach, the doctor needs to visit the patient’s
wards for checking the status of patient should be admitted in
the hospital for a period of time and the doctor should be
present near the patient all the time. In order to avoid such
problems we can make use of the present technology in a
smarter way. By this we can save many lives by providing a
quick service.

1.INTRODUCTION
Internet of Things is a network of devices which is builtwith
embeddedsystem,electronic things, actuators,sensors and network
connectivity and which enables these objectivesto exchange
and collect the data information. Using internet of things
objects can be sensed and controlled from existing network.
Also direct integration can happens between computer
based system and physical network.[1].The increasing
generation needs empowered gadgets by wireless
technology which includes Bluetooth, Radio frequency
identification, embedded sensors and many more. The
normal human life can be change to smart life using the new
technologies of IOT. Internet of Things is used to monitor all
patients at any situation. Health plays important role in our
life. Since from decade the healthcare has draw significant
amount of attention. The patients who are suffering from
chronicle diseases they need to take check-up daily.
Manually it is very difficult to keep track on the heart beat
abnormalities of the patient. A normal heart rate for
adult’s ranges from 60 to 100 beats per minute while for a
above or below this range of heart beatleadstoheartattacks
and the normal body temperature is ranges from
97°F(36.1°C) to 99°F to (37.2°C). A temperature
over100.4°F (38°C) it means the person is suffering from
fever caused by an infection or illness. The patients are not
well known with the manual treatment which doctors
usually prefer for checking the heartbeat. There are several
devices available in the market in order to keep track on the
internal changes of the body. But therearemany limitations in
the maintenancedue to the size of the device, heavy cost, and
the portability of the device. So in patient health monitoring
system we are designing a small size, low costanda portable
device in order to provide a continuous monitoring of the
patient health.
2. BLOCK DIAGRAM
The diagram of the project consists of Raspberry pi3,
Temperature sensor (DHT11), Heart Rate Sensor, HDMI
Display, Buzzer, Wi- Fi, Adafruit. The proposed method of
patient health monitoring system is to monitor patient’s
body temperature, heart rate using Raspberry Pi3. The
temperature sensor(DHT11) senses the temperature from
the patient’s body and send theinformationtotheraspberry
pi3. The heart Rate sensor collect the heart beat from the
patient, the information obtained fromtheheartRatesensor
is in the analog form, to convert it into digital form, we are
using Analog-to-Digital Converter(ADS1115) the obtained Digital

output send to the raspberry pi3 through serial data line of
ADS1115 to theraspberrypi3.Theoutputobtainedfromraspberrypi3
is displayed at the HDMI display which is again sent to
Aadafruit through Wi-Fi. After connecting internet to
the Raspberry Pi3 it acts as a server. Then the server is
automatically sends data to the website. Using IP address
anybody can monitor the patient’s healthstatusanywherein
the world using laptops, tablets and smart phones. If these
parameters are goes to abnormal it will automaticallysendalert
messagetothedoctorsandrelativesthrough Adafruit, so that the
doctor can instantly take the action on these abnormalities.
And simultaneously the buzzer is turn on in order to alert
the caretaker who is present in the premises.
3. IMPELEMENTATION METHODOLOGY
3.1. Hardware Discription
A.RASPBERRY PI 3
Raspberrypi3isacreditcardsizesingleboardcomputer with 40 pin
extended GPIO, Broad cam BCM2387 chipset,1.2GHz Quad-
core ARM Cortex-A53(64Bit), 802.11 B/G/N Wireless LAN
and Bluetooth 4.1, GPU(Dual Core Video core IV®
Multimedia Co-Processor), Camera connector, Display
connector,Memorycardslot,1GBLPDDR2memory,Ethernetport, USB
host, Micro HDMI on it. Raspberry pi3 is a general purpose
computer usually with Linux OS.
B. Temperature and Humidity Sensor (DHT11):
The DHT11 sensor is digital temperature and humidity
sensor. It is very popular because it is very cheap but still
providing great performance. The temperature rangesfrom0to 50
degrees Celsius with +/- 2 degrees accuracy. And the
Humidity range is from 20 to 80% with 5% accuracy. The
sampling rate is 1Hz or one reading every second. The
operating voltage is 3 to 5 volts, the max current used when
measuring is 2.5mA. It includes humidity in order
measurement to measure the humidity and an NTC
temperature measurement component for measuring
Temperature. It offers excellent quality, fast response, anti-
interference ability and cost-effectiveness.
C. Analog-To-Digital Converter (ADS1115):
The ADS1115 is a 4-channel breakout board, it is perfect for
adding high resolution analog to digital conversion to the
raspberry pi 3. It is also a 4-channel analog to digital
converter and it utilizes the I2C proto call with selectable
addresses. It has a wide supply ranges from 2V to 5.5V .The
current consumption is low 150μA (Continuous Conversion
Mode), Operating Temperature Range:–40°C to+125°C. The
connection of this ADC with the raspberry pi3board runs at
the Debian based Raspbian operating system. But the reality
is we are using the Linux system.
D. Heart Rate Sensor:
The heart rate sensor is based on the principle of photo
phlethysmography. It measures the variation in the volume
of blood through any regions of the body which causes a
change in the light intensity through that region (a vascular
region). When the index finger is placed on the heart beat
sensor, the variation in an optical power takes place when
the light falls on the index finger is scattered or absorbed
during the path through the blood as the change in
heartbeat.
E. Piezo Electric Buzzer:
The piezo electric buzzer is an electronic device used to a
piezo electric vibration plate in a plastic case (resonator). In
this produce a sound. This buzzer is prepared by
incorporating project, this buzzer is used to alert the
caretaker during the critical condition of the patient and the
sound obtained by this buzzer indicates that the patient
health is in a risk.
3.2. Web server
Adafruit:
In our project we are displaying the information about
patient health related parameters like temperature and
heart rate in the website. Using IP address anybody can
monitor the patient’s health status anywhere in the world
using laptops, tablets and smartphones.Adafruit webpageis
used for displaying the information of the project.
3.3. Proposed System
In A Secure IOT Based Modern Healthcare System, Internet
of things is used to give flexibility and fast operational speed
to get expected outcomes. In this, hardware elements are
used that are Raspberry pi 3, pulse sensor, Temperature
sensor etc. and more sensors also can be used to detect
various biological functionality. In this Hardware elements
are integrated with software system that controls the
hardware and report generation. Pulse sensor is Easy pulse
1.1 is used and general temperature sensor is used to detect
temperature. By using This System, we can detect abnormal
conditions in human body at real time. Raspberry pi3 is
device which is connected with sensors, sensors are
connected with human bodies, and this raspberry pi3 is
connected with software systems by using wireless
connection. When all elements are connected together,
sensor senses data from human body,thensendsthatdata to
server. After that these data is compares with standards
values that are already stored in system. According to that
normal and abnormal conditionscheckingisperforms.Andif
there are any abnormalities are occurring the it sends
message immediately to doctor toavoidcritical situations. In
this System Administrator is there to control system, it can
control new patient’s entries and doctor’s entries, when it
will get data from sensors and stores in database is
displayed in separate IOT page which periodically loaded

and fetches data from database. Time interval is ranging
from 5 to 10 second. When abnormalities occur, message is
get send to doctors or patients 1 sec. In this system, we
should have to connect system and hardware device and
server centrally.
