CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
It is not always feasible for a patient to keep track of their heartbeat at all times. A change
in the heart beat count would help the doctors to identify that the patient is suffering from any
kind of abnormality. This can be easily taken care if notified at the correct time. For this purpose
the project has been developed to keep a track on the heartbeat of the patients at all times. The
product to be developed should be light weight and small in size for the easy carrying of the
device at all times. If at any point of time a change occurs in the heart beat of the patient a
notification is instantly sent to the person in charge of the patient and the respective action can be
taken up.

CE 2.2.2 Objectives developed for the project
The “Wireless Patient Health Monitoring System” has been developed with the following
objectives in mind:
 To make the device as small as possible
 To provide the patient with round the clock maintenance and monitoring of their heart
beat.
 To provide a notification about the changes in the heart beat of the patient as soon as
any abnormality of the heart beat count.
CE 2.2.3 My area of work
The work which I had undertaken for the completion of this project is for the
development of the hardware portion of the project. The hardware portion had been further
divided up into two sections. The hardware portions then became the transmitter and the receiver
of the module. I had taken up the work for the development of the transmitter section of the
module. At the end of the project completion I had helped in the testing of the device and then
documented the complete procedure for the submission at my university.

CE 2.2.5 My responsibilities throughout the project
I was responsible for the development of the hardware module of the project. More
specifically I had worked on the development of the transmitter section of the project. I had then
conducted several tests on the project module to debug any abnormalities in the project module. I
had also helped my team mates for the completion of the project on the correct timeline. I had
then helped in the testing of the device to know the issues which were still there in the device. I
had then compiled the writing of the project documentation for the completed project.

CE 2.3 Distinctive Activity
CE 2.3.1 Comprehending the theory of the project
I had implemented the transmission module of the hardware section of the device. The
transmitter was to collect the data from different collectors of the project module and then
convert it into digital values for further processing of the data. The digital data is then transferred
with the help of zig bee module along with the μC. The receiver module need not be kept in
close contact for the transferring of the data. The receiver has been designed in such a way so as
to collect the data from the air and then to transfer them to the PC by using the serial
communication COM port. The transmitter circuit consists of a heart beat monitoring sensor
along with the help of LM358. The monitoring system has been developed with the help of a
microcontroller 8051. The device works when the patient places the tip of his finger between the
LED and the photo resistance receiver. The Analog voltage is further processed by the amplifier
LM 358 which produces the digital pulses. A software is then used to count the number of heart
beat in the signal and the result is displayed on the LCD. For the temperature sensor an LM 35
has been used in the device. The temperature is recorded in centigrade and provides more
accurate result than a thermistor. For the viewing of information and messages form the device a
LCD had been installed into the module of size 16 X 2. After all the information has been
collected from the devices it needs to be transferred to the PC. This is done with the help of Zig
Bee module. This has been used due to its low cost and low power consumption properties.
CE 2.3.2 Engineering knowledge and skills applied in the project
Once all the different components of the device were collected the device was now ready
to be compiled. To follow a simple flow of the work and connection I had developed a block

diagram of the system. I had then proceeded to design separate block while following the
diagram. I had then tested out each of the blocks that had been created so that they are working
correctly. I had then collected the printed circuit boards (PCB) to make the core of the system.
For the PCB I had used the Easily Applicable Graphical Layout Editor (EAGLE). There are steps
that can be followed for the designing of the PCB. After the PCB has been created the different
blocks are then soldered onto the board for the completion of the system.
CE 2.3.3 Accomplishment and task performed
I was responsible for the development of the transmitter module of the project that is to
be responsible for the transmission of the information to be collected from the different
components of the project. The temperature and the heart beat counts from the transmitter is sent
to the PC with the help of the COM port. The LCD will be able to display the corresponding
message based on the programming. The programming is to be embedded into the project
module for the decision making procedures of the values received form the transmitters. I had
connected all the different modules of the project to compile the complete project. After my
work I had helped in the calibration of the receiver device that would work with the complete
project.
CE 2.3.4 Identified issues and their solutions
2.3.4.1 Issues
The major issues which I had faced during the implementation of the project the
transmission of the data from the devices and the transmitter modules to the receiver modules.
The data was to be then sent to the online portal for the viewing of the data in a graphical format.

2.3.4.2 Solutions
The problem was raised from the unavailability of the connection protocol of the Zig Bee
module. The module was found to be missing when I was debugging the project. I had then
consulted with my team mate who was responsible for the software module of the project and
told him to implement the missing module into the system.
CE 2.3.5 Plan to produce creative and innovative work
I had provided with the idea of implementing multiple SMS receiver for a single module
for the receiving of the emergency notifications. I had first thought about only the
implementation of the heartbeat sensor in the project. Later on with the help of my team mates I
was also able to implement the temperature sensor on the device module. This implementation
will drastically help the biomedical field.
CE 2.3.6 Collaborative work
I had collaborate with my teammates to produce the best quality project and provide the
same as my project for my bachelor’s degree. I had also received help from my project
supervisor of my university for the understanding of the different modules of the project and for
the purpose of correct presentation of the project. I had initiated many of the project team
meetings with my project supervisor for the discussion of the issues that were being faced by us
during the implementation of the project.

CE 2.4 Project Review
CE 2.4.1 Project Overview
I had analysed the “Wireless Patient Health Monitoring System” for the implementation
of the temperature and the heart beat form the patients with the help of GSM, SMS and ZigBee
module. If any type of abnormality in the heart beat is detected then the same is notified to the
patient’s guardian with the help of SMS system. The hardware was implemented successfully
and the output and the results were studied. Several tests were conducted on the device module
to discard any kind of issues which may have been overlooked during the project development
process.
CE 2.4.2 My contribution to work
For the development of the project I had worked on developing the hardware
transmission module of the project. The transmitter module comprised of the electronic
components that were responsible for the transmission of the collected data from the patient’s
body. I had then conducted several tests on the project module to find any bugs which may have
occurred during the development of the project. In the end, I had compiled the project
documentation for the submission in my university.
