This document describes an IoT-based health monitoring system that uses a pulse oximeter and ECG sensor. The system aims to remotely monitor patients' vital signs like heart rate and body temperature. It uses an Arduino board connected to sensors to collect medical data, which is then transmitted via WiFi to a cloud database. This allows doctors to continuously monitor patients' health from anywhere. The system stores collected data over time to analyze health trends. It provides affordable health monitoring without requiring hospital visits for regular checkups.

2. INTRODUCTION OF THE PROJECT WORK
2
• The healthcare sector is going through a huge change, with digital capabilities
changing the way doctors interact with their patients.
• However, we note that these devices are quite expensive and it is difficult to
find these devices used by poor people, who are facing the biggest part of
diseases burden.
• The concept of the IOT entails the use of electronic devices that capture or
monitor data and are connected to a private or public cloud
• Medical data such as blood pressure and heart rate are collected by sensors on
peripheral devices; these data are transmitted to healthcare providers or third
parties via wireless telecommunication devices.

3. OBJECTIVES
3
• To detect the using heart beat sensing based on IOT
technology
• To develop health monitoring system i.e. it
measures body temperature and heart rate.
• To design a system to store the patient data over a
period of time using database management in IoT.

4. ABSTRACT
4
Monitoring and Recording of various medical parameters of patient
outside hospitals has become Widespread phenomenon. The Reason
behind this project is to design a system for monitoring the patient’s
body at any time using internet connectivity. The function of this
system is measuring and detecting the heart pulse rate of the patient’s
body by using Heart beat sensors and sends the values to IOT Cloud
platform through WIFI-Module. All information about the patient heart
pulse rate and health will be stored on the cloud, it enables the doctors
to monitor patient’s health, where the doctor can continuously monitor
the patient’s heart condition on his Smart phone.This project is
implemented with Arduino Controller.

7. EXISTING SYSTEM
• This system has been designed to take several inputs to measure
physiological parameters of human such as temperature, heart rate,
detection of any fall and the saline level.
• The inputs from the sensors are integrated and processed. The results are
sent through the Zig bee Module to a host computer, which stores the
data into an Access Database.
• The values can then be displayed on the Graphical User Interface (GUI)
running on a computer. If it is inferred that the person is medically
distressed, an alarm may be generated.
• The program is a user interface, allowing a report on the current status
of the individual.

8. PROPOSED SYSTEM
• In this proposed work the vital parameters such as temperature,
ECG and heart beat readings which are monitored using Arduino
Uno.
• Here patients body temperature , ECG and heart rate is measured
using respective sensors and it can be monitored in the screen of
computer using Arduino Uno connected to a cloud database system
as well as monitored anywhere in the world using internet source.

9. CONTINUED…
• The proposed method of patient monitoring system monitors
patient’s health parameters using Arduino Uno.
• After connecting internet to the Arduino Uno, it is connected to
cloud database system which acts as a server.
• Then the server automatically sends data to the receiver system.
Hence, it enables continuous monitoring of the patient’s health
parameters by the doctor.

• Arduino is an open-source electronics platform based on easy-to-use hardware
and software.
• Arduino boards are able to read inputs - light on a sensor, a finger on a button, or
a Twitter message - and turn it into an output - activating a motor, turning on an
LED, publishing something online.
• The Arduino Uno is a microcontroller board based on the ATmega328.
• It has 20 digital input/output pins, a 16 MHz resonator, a USB connection, a
power jack, an in-circuit system programming (ICSP) header, and a reset button.
• The Arduino language is C++, but it is very different from most C++ varieties.
• The Arduino language has a lot of abstraction built in, especially in the hardware
interfaces, which makes it very simple to use.
