Abstract— Now-a-days, a growing number of people in a developing countries like India forces to look for new
solutions for the continuous monitoring of health check-up. It has become a necessity to visit hospitals frequently
for doctor’s consultation, which has become financially related and a time consuming process. To overcome this
situation, we propose a design to monitor the patient’s health conditions such as heart beat, temperature, ECG and
BP and send the message to guardian using GSM. In the recent development of internet of things(IoT) makes all
objects interconnected and been recognized as the next technical revolution. Patient monitoring is one of the IoT
application to monitor the patient health status. Internet of things makes medical equipments more efficient by
allowing real time monitoring of health. Using IoT doctor can continuously monitor the patient’s on his smart
phone and also the patient history will be stored on the web server and doctor can access the information
whenever needed from anywhere.

I. INTRODUCTION
Now-a-days, the medical electronics-sensors (E-sensors) are playing an important role in health care centers. The
patient electronics-health (E-health) monitoring is one of the major advancements in research field. Here we use
the temperature sensor, heartbeat sensor and ECG sensor to monitor the patient’s body temperature, pulse and
heart rate respectively. Hence like the use of thermometer in home to check body temperature before doctor’s
consultation, this proposed model (devices) can be used to check the patient’s health condition in home as first-
aid information to the concerned patient otherwise now-a- days consulting doctors or going to diagnosis centers
become very costly in terms of financial aspect. To minimize this situation, we describe the design of a
SST89E516RD2 microcontroller based advanced/high performance integrated health portable monitoring system.
Like one parameter say Heart rate of the patient is measured by placing the index finger on IRD (Infra-Red Device)
sensor and the pulse rate is then measured and displayed on LCD. The device sends messages when the parameter
value exceeds the provided cut-off value. This cut-off value or threshold is given by the programmer during coding
of the LPC-2148. The standard heart beat ranges between 60-100 pulses/min and standard temperature ranges
between 18°C to 38°C. The Heart Rate, ECG, Brain tumor and the Body Temperature information is then sent to
the authorized person through GSM.

The interconnection of these embedded devices (including smart objects), is expected to usher in automation in
nearly all fields, while also enabling advanced applications like a Smart Grid. Things, in the IoT, can refer to a wide
variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in
coastal waters, automobiles with built-in sensors, or field operation devices that assist fire-fighters in search and
rescue.
4.1 Functioning Of Internet Of Things (Iot)
The Internet of Things is the expansion of the current Internet services so as to accommodate each and every
object which exists in this world or likely to exist in the coming future. This article discusses the perspectives,
challenges and opportunities behind a future Internet that fully supports the “things”, as well as how the things
can help in the design of a more synergistic future Internet. Things having identities and virtual personalities
operating in smart spaces using intelligent interfaces to connect and communicate within social, environmental,
and user contexts. There are several fuzziness about the concept of Internet of Things such as IoT can be broken in
two parts Internet and Things.
4.2 IoT Application
 Machine-to-machine communication
 Machine-to-infrastructure communication
 Telehealth: remote or real-time pervasive monitoring of patients, diagnosis and drug delivery
 Continuous monitoring of, and firmware upgrades for, vehicles
 Asset tracking of goods on the move
4.3 Methodology
FIGURE 3 Methodology of PHMS using IoT Devices
In this project we have temperature, blood pressure, ECG and heart beat readings which are monitored using
Microcontroller. These sensors signals are send to Microcontroller via amplifier circuit and signal conditioning
unit (scu), because the signals level are low (gain), so amplifier circuit is used to gain up the signal and transmit
the signals to the Microcontroller. Here patients body temperature, blood pressure , ECG and heart rate is
measured using respective sensors and it can be monitored in the screen of computer which is monitoring
through anywhere in the world using internet source. The proposed method of patient monitoring system
monitors patient’s health parameters using Microcontroller. After connecting internet it acts as a server. Then the
server automatically sends data to the website. Using IP address anybody can monitor the patient’s health status
anywhere in the world using laptops, tablets and smart phones. If these parameters goes abnormal it will
automatically sends alert SMS to the doctors and relative.
