In this time of epidemic Healthcare is given extreme importance. IOT based health monitoring is the best solution. In our project a portable physiological checking framework is displayed, which can constantly screen the patients pulse rate, temperature and oxygen. The temperature sensor measures the body temperature and oximeter measures the oxygen level and pulse of the patient when the patient is in contact (fingertip) with the sensors. It is a non-stop measuring instrument which sends data of patient to the IOT server using the Wi-Fi Module. In this system the authorized personal can access these data stored using IoT server and based on these values received, the diseases are diagnosed by the doctors from a distance.
I. INTRODUCTION
Health monitoring is a essential problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices that can monitor the health of patient over internet. Health experts are also taking advantage of these smart devices to keep an eye on their patients. With tons of new healthcare technology start-ups, IoT is rapidly revolutionizing the healthcare industry. IOT based patient health monitoring system is a generic term given to any medical equipment that has internet capability and can measure one or more health data of a patient who is connected to the device such as heartbeat, body temperature, blood pressure, ECG, Pulse rate etc. Our device measures temperature, blood oxygen and heart rate. The equipment can record, transmit and alert if there is any abrupt change in the patient’s health.
II. LITERATURE REVIEW
This is especially important for patients with chronic diseases and patients that require regular monitoring of vital parameters. Using web or mobile application, patients’ data can be collected easily and efficiently, at the same time providing access to them from any location. Visualization of this data as well as tracking the progress and facilitating communication between patients and doctors, are considered as a great advantage of this solution. Taking the medicine on time is considered to be a high priority for patients. Failure to take the medicine on time cannot only delay recovery, but can worsen the symptoms of an existing illness or cause serious side effects. In this context the use smart TV application for showing reminders and notifications, is very important. Our next step will be conducting the evaluation study with the end users in order to get the feedbacks from them, which will be used for further system improvement.
III. COMPONENTS SPECIFICATIONS
A. LM35 Temperature Sensor
LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.
B. MAX30100 Oximeter
Pulse oximeter is a method for monitoring a person’s oxygen saturation and heart rate. Basically Oximeter calculates the percentage oxygen saturation in the blood on basis of amount of different light absorb in it. In this approach, a sensor device is placed on a thin part of the patient’s body, usually a fingertip or earlobe, or an infant’s foot. Fingertips and earlobes have higher blood flow rates than other tissues, which facilitates heat transfer.
C. ESP8266 WI-FI Module
The ESP8266 is a very user-friendly and low-cost device to provide internet connectivity to your projects. The module can work both as an Access point (can create hotspot) and as a station (can connect to Wi-Fi), hence it can easily fetch data and upload it to the internet making the Internet of Things as easy as possible. It can also fetch data from the internet using API’s hence your project could access any information that is available on the internet, thus making it smarter. Another exciting feature of this module is that it can be programmed using the Arduino which makes it a lot more user friendly.
D. Arduino UNO
Arduino is an open source physical computing platform based on a simple input/output (1/0) board and a development environment that implements the Processing language. Arduino can be used to develop standalone interactive objects or can be connected to software on your computer. Arduino hardware is an open-source circuit board with a microprocessor and input/output (1/0) pins for communication and controlling physical objects (LED, servos, buttons, etc.).The board will be powered via USB or an external power supply which in turn allows it to power other hardware and sensors.
IV. BLOCK DIAGRAM
The temperature sensor, oximeter, power supply and ESP8266 are connected to the Arduino UNO. The temperature sensor measures the body temperature, the pulse sensor will measure the pulse and oximeter measures the oxygen level of the patient when the patient is in contact (wrist) with the sensors. The Arduino will process the code and display the data of the patient to LCD display. The Wi-fi module ESP8266 provides internet connectivity through which the data will be monitored on the IOT server. Thus, the doctors and relatives of the patient can access the data and monitor the health of the patient remotely and take necessary measures accordingly.
V. HARDWARE DESIGN
A remote health monitoring system using IOT is proposed where the authorized personal can access these data stored using any IoT platform and based on these values received, the diseases are diagnosed by the doctors from a distance. The LM35 Temperature sensor are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature, has an advantage over linear temperature sensors calibrated in Kelvin. The ESP8266 is a very user-friendly and low-cost device to provide internet connectivity to your projects. It can also fetch data from the internet using API’s hence your project could access any information that is available on the internet, thus making it smarter. Arduino hardware is an open-source circuit board with a microprocessor and input/output (1/0) pins for communication and controlling physical objects (LED, servos, buttons, etc.). The board will be powered via USB or an external power supply which in turn allows it to power other hardware and sensors. The temperature sensor, blood pressure sensor, oximeter, power supply and ESP8266 are connected to the Arduino UNO. The sensor measures the parameters of the patient when the patient is in contact with the sensors. The Arduino will process the code and display the data of the patient to LCD display. The Wi-fi module ESP8266 provides internet connectivity through which the data will be monitored on the IOT server.
Limitations: It is not accessible for everyone. It requires good broadband connectivity, which is hard to achieve for small healthcare institutions and rural hospitals.
Vi. METHODOLOGY

The Arduino will process the code and display the data of the patient to LCD display. The Wi-fi module ESP8266 provides internet connectivity through which the data will be monitored on the IOT server. Thus, the doctors and relatives of the patient can access the data and monitor the health of the patient remotely and take necessary measures accordingly.
VII. EXPERIMENTAL RESULTS
In the above mentioned system we have proposed a health monitoring system which is IOT based. User friendly and bridges gap between doctor and patients. The system is simple, Power efficient. Practical application of the system is superfine in rural areas as there would be no need for the patients to get their continuous follow-ups.
