This document describes an IoT-based health monitoring system created by three group members. The system uses sensors to measure a patient's heartbeat and temperature, which are sent wirelessly to a monitoring center. The monitoring center allows for real-time analysis of the vital sign data and emergency alerts. The system aims to allow doctors to remotely monitor patients at low cost using embedded technology.

4. Introduction
 This health monitoring system is composed of two parts, which
are portable remote medical monitoring unit and the
monitoring center.
 In this project, we propose a remote medical monitoring system
for heart beat rate and temperature data.
 Monitoring center is a station which consists of real time
analysis and a warning mechanism for emergency and diagnosis.

5. DRAWBACKS OF EXISTING SYSTEMS
 The systems are not portable.
 The patients or the family members of the patients can’t able
to understand the analog signals.
 Complex system and difficult to operate.

6. MAIN OBJECTIVE
 The specialist at a distance can monitor the patient condition
so that he/she can save the life.
 This system is to be available at reasonable prices.
 Embedded technology is to be use for monitoring the patient
condition easily.
 Easy to operate.

9. ATMEGA 328P
The ATmega328 is a single-
chip microcontroller created by Atmel in
the megaAVR family (later Microchip
Technology acquired Atmel in 2016). It
has a modified Harvard architecture 8-
bit RISC processor core.

10. SENSORS
HEART RATE SENSOR TEMPERATURE SENSOR (LM35)
Pulse Sensor is a well-designed plug-and-
play heart-rate sensor for Arduino. It can be
used by students, artists, athletes, makers,
and game & mobile developers who want to
easily incorporate live heart rate data into
their projects. The sensor clips onto a
fingertip or earlobe and plugs right into
Arduino. It also includes an open-source
monitoring app that graphs your pulse in
real time.
LM35 is a temperature measuring device
having an analog output voltage proportional
to the temperature. It provides output voltage
in Centigrade (Celsius). It does not require any
external calibration circuitry. It is a 3-terminal
sensor used to measure surrounding
temperature ranging from -55 °C to 150 °C.
LM35 gives temperature output which is more
precise than thermistor output.

11. GSM SIM MODULE MAX232
A GSM module or a GPRS module is a
chip or circuit that will be used to
establish communication between a
mobile device or a computing
machine and a GSM or GPRS
system. The modem (modulator-
demodulator) is a critical part here.
The MAX232 is an integrated circuit first
created in1987 by Maxim Integrated
Products that converts signals from
a TIA-232 (RS-232) serial port to signals
suitable for use in TTL-compatible
digital logic circuits. The MAX232 is a
dual transmitter / dual receiver that
typically is used to convert the RX, TX,
CTS, RTS signals.

12. 16*2 LCD DISPLAY POWER SUPPLY
An LCD is an electronic display module
which uses liquid crystal to produce a
visible image. The 16×2 LCD display is a
very basic module commonly used
in DIYs and circuits. The
16×2 translates o a display 16
characters per line in 2 such lines. In
this LCD each character is displayed in
a 5×7 pixel matrix.
Here we are using a 5V DC power
supply. In general, a 5VDC output is
obtained from a 50VAC or 240VAC
input using a combination of
transformers, diodes and
transistors.

13. WORKING OF THE SYSTEM
 There are mainly two parts of the system, one transmitter and
the other one is receiver.
 In the transmitter, We have heart beat sensor and the other
temperature sensor.
 All the sensor are connected to the patient.
 The microcontroller monitors all the system in the transmitter
if any abnormality in the patients condition then it sends the
signal so that the receiver will capture the signal and will work
according to that.

14. ADVANTAGES
 Bridging the gap between doctor and the patients.
 Best to be used on rural areas.
 Compare with compact sensors it gives better performance.
 Easy to operate.
 Low cost.
 Portable.

15. DISADVANTAGES
 The system may get hacked because the data security
system is not included.
 If power supply fails then the circuit will not work.

16. APPLICATIONS
 It can be used in ICUs, operation theatres etc for monitoring
the health condition of the patient.
 It can also be used in old age homes to monitor the various
parameters of a sick person.
 It can be used in daily life to maintain a healthy life style.

17. FUTURE SCOPES
 Multiple parameters like Blood Pressure, retinal size, age and
weight can be included as controlling parameters in the future.
 The whole health monitoring system , which we have proposed
can be integrated into a small compact unit as small as a cell
phone.
 This will helps the patients to easily carry this device with them
wherever they go.

18. CONCLUSION
 Wireless technology is emerging as a significant element of next
generation healthcare service.
 Portable and easy to use.
 Prevention is better than cure.
 Modern technologies have developed that promotes comfortable
and better life which is disease free.
