CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
The project of Design and Fabrication of Health Monitoring System was my third
important project in engineering career. Health plays the most important role in everyone’s life
and thus checking of the usual conditions like temperature, pressure rate and heart beat of the
patient is extremely vital. This project system is comprised of two major parts, namely,
transmitter (at the patient side) and the receiver (at the doctors side). The main benefit of this
project is that the doctors do not have to check the patients with various different machines and
they can use this device for multiple purposes.
CE 3.2.2 Objectives developed for the project
The project of Design and Fabrication of Health Monitoring System had several
objectives. The most important objectives for this particular project are as follows:
 To design and fabricate a health monitoring system.
 To implement the system for monitoring patient’s health.

 To monitor temperature, pulse rate and heartbeat of patients.

CE 3.2.4 My responsibilities throughout the project
I had various responsibilities in this project. My first responsibility was to document the
entire project. I even arranged for workshops and trainings for my team members and made sure
that the project was executed with utmost professionalism. My next responsibility was to assist
the project leader and help him in scheduling the project. I also made the project plan and
budget.

CE 3.3 Distinctive Activity
CE 3.3.1 Comprehending the Theory of the project
The main job of this project is the development of a system that is significantly
supplemented with a particular real time system of the wireless monitoring, is designed as well
as implemented via network of GSM, and has the ability for recording and also transmitting the
signals of any patient. The major objective of this particular project is the providing of medical
monitor for each and every patient irrespective of the time and the designing of the patient
tracking system by utilizing the GSM to give a specific wireless system for the purpose of
monitoring all the parameters of a patient like temperature, pressure rate and heartbeat. The
entire architecture of the system is comprised of two major parts. They are given below:
i) Transmitter side: the transmitter side is consisted of three distinct kinds of sensors like
the sensor of heart beat, sensor for temperature, and the sensor of pressure rate. These three
sensors are utilized for measuring the signals from a human body like temperature, heartbeat,
heart signal, and temperature. Once this measurement is done, the analogue signals are
transformed to digital signals for further comparison with all the actual signal. When any type of
mismatch is occurred within the actual and measured signal, it will be considered as an
emergency. The processor of ARM LPC 2148 plays the most significant role to control each and
every device.

ii) Receiver Side: The receiver side comprises of Buzzer, RF receiver, GSM, and a LCD.
The details of the patients are solely displayed on the LCD screen and they are compared with
actual values and for understanding whether they are normal or not.

The raw materials of this project are as follows:
i) Hardware Description: The microcontroller accesses the data. In this project, ARM
controller is utilized. For the purpose of measuring the patient’s temperature there is a
temperature sensor, which converts the sensor output into the electrical form.
ii) ARM 7-LPC2148: This processor also provides a unique strategy of architecture
called the Thumb that makes it properly suited to the applications of high volume with all types

of memory restrictions, and applications. The main idea behind this Thumb is an extremely
reduced set of instruction.
iii) The standard set of 32-bit ARM: The Thumb set’s length of 16-bit instruction enables
it in approaching double of density of the standard code of ARM while keeping maximum of the
performance advantage of ARM on the traditional 16-bit processor utilizing 16-bit registers.
iv) Sensor of Temperature: The series of LM35 is absolutely precision integrated circuit
sensors, where the voltage of output is directly proportional to the temperature of Celsius or
Centigrade.
v) Heartbeat Sensor (LM 358): this particular sensor is designed for giving digital output
to the heart beat the moment one finger is kept within it. The output for digital could be easily
linked directly to ARM for measuring the rates of BPM or Beats in one Minute. It eventually
does its job on the core standard fir light modulation.
vi) Pressure Rate Sensor: This particular sensor is usually dependent on the piezio
electric effect principle. This sensor is responsible for the overall measurement of the pressure
rate of a human being and monitors at that very moment, when it does not get proper response.
vii) RF Module: Radio frequency or RF is the specific term, which refers to the
alternating current or AC that have various features like, when the current within the system is
input into an antenna, automatically an EM or electromagnetic field is generated that is suitable
for the wireless broadcasting and communications.
viii) GSM Hardware: this is the most important part of the entire project. The main part
of the data communication regarding this system eventually lies within the terminals of wireless

communication control, which utilizes the modules of GSM for transferring the long-distance
data reliably and extensively. SIM300 could be easily integrated with the broad applications
range. The SIM300 module is a specific engine for Tri-band GSM or GPRS, working over
various frequencies like PCS1900 MHz, DCS 1800 MHz, and EGSM 900 MHz. With the help of
a minute configuration for the 40mm x 33mm x 2.85 mm, SIM300 can easily fit approximately
all the space needed in this application. Thus, the MCU can easily be linked with the various
modules of GSM modules appropriately via all the serial interfaces.
There are various advantages in this project. It gives high level safety to the human life
and even gives easy data retrieval for accidents. It is extremely low of cost and less complicated
system to install and apply.

my doubts were absolutely clarified. My team members and team leader were responsible for the
completion of the project. My knowledge of electronics engineering has helped me to execute
my responsibilities in the project perfectly.
CE 3.3.4 Identified issues and their solutions
CE 3.3.4.1 Issues
The most significant problem that I faced in this project of Design and Fabrication of
Health Monitoring System was in the designing part. The team member, who was supposed to

make the design, could not do it properly and thus, the output was coming erroneous. My team
members were unable to find the problem within the project.

present in the design. I therefore, myself, made the entire design of the project and thus was
successful in completing the entire project perfectly.
CE 3.3.5 Plan to produce creative and innovative work
Our plan was to complete the project of Design and Fabrication of Health Monitoring
System perfectly. The plan was to produce creative and innovate work by working together with
my fellow team members and team leader and segregating the work.

includes the optimization of ARM9, ARM 11 and hardware system. This particular system has
several benefits like the lower operation costs, easy to utilize, wide area range, large capability,
effective as well as strong expandability. The up gradation of this particular setup is extremely
