CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
I had conducted this project study to implement a data logging system which provides
flexibility, customization and combination to WSN. Data logging is a general measurement
application which measure and record of physical as well as electrical parameters. I had
considered some of the data such as voltage, temperature, flow, current, power, pressure and
resistance. The data logging applications acquire and record of signals, involving with
combination of data sharing. Data logging system is combined with storage capabilities of the
data loggers to archive, analyze, and report and display of capabilities of modern PC. This PC
based data logging system is used to provide wide range of measurement types, analyzing the
capabilities as well as reporting tools. Within the PC based data logging system, data acquisition
is accomplished by measuring the hardware such as sensor, signal connectivity and conditioning.

CE 3.2.2 Objectives developed for the project
Following are the objectives of the project study:
 To implement data logging system with WSN
 To convert of physical parameters into electrical signals
 To describe components of hardware measurement with which the sensors are connected
towards logging system
CE 3.2.3 My area of work
I had provided an in-depth study on the WSN applications in order to monitor as well as
control of the environmental data. I had also analyzed the environmental data such as voltage,
temperature, flow, current, power, pressure and resistance for data logging. I had controlled
entire sensor network with no retrieve of the sensors once it is installed. I had implemented the
data logger for WSN which allows real time acquisition of data and storage on acquired data into
flash memory.

CE 3.2.5 My responsibilities throughout the project
My responsibilities as a telecommunication engineering is to implement of data logging
with WSN. I had analyzed the features of control system which is associated with sensory of the
data acquisition system. I had monitored the flow of data and extracted significant data from the
raw data. I had extracted the environmental data and exported it whenever required. I had
protected the data from any type of unauthorized access by third party person. I had also used of
MATLAB for conducting of WSN test bed.
CE 3.3 Distinctive Activity
CE 3.3.1 Comprehending the Theory of the project
WSN comprises of set of sensors which read the environmental parameters such as
vibration, temperature, magnetism, light and other parameters. I had analyzed that the data
logging services are focused to collect of environmental data to monitor the natural and also

human made elements. The environmental parameters build a real time system for detecting the
target and tracking with use of central monitoring units. I had determined that real time
monitoring is not adequate. It can store data for doing further analysis as well a processing at
afterward time. The sensors are programmed to save the data and send it to organize the nodes. It
avoids congesting the communication channel an enormous amount of transmissions, when there
is higher number of sensors. Data logger is software which input the data coming from sever
directly into the log file created by means of it. It also allows collecting information coming from
the device into real time.

CE 3.3.2 Engineering Knowledge and Skills applied in the project
I had knowledge to process the data and the information which are extracted from it. The
data are used in future for further reference as well as for analysis. I had stored the data into
storage system. I had knowledge to develop of data acquisition system for competent data
collection from the sensors. I had also developed of data logging scheme as well as database.
Report generation as well as historical data trends is developed for presentation of data. I had
conducted study to implement of different data acquisition and also data logging techniques,
current data trending and setting of various security levels.
CE 3.3.3 Accomplishment and task performed
I had involved into the project study by analyzing the data logging applications involved
to acquire as well as record of the signals. It involves combination of online and offline analysis,
display, generation of report and sharing of data. The data logging applications are required to
acquire and store of those data types. With an advancement over the modern computer, PC based

data logger system is evolved. I had determined that this type of data logging system can
combine with acquisition as well as storage capabilities to stand alone with the data loggers to
achieve, analyze, report as well as display the capabilities of the modern PC. This PC based
logging system provides with wide range of measurements types, capability to analyze as well as
reporting of tools.
I had performed data acquisition by measurement of the hardware such as sensors, signal
connectivity and conditioning. I had used of sensors to convert of physical parameters into the
electrical signals. I had used of software to do online analysis. I had performed the offline
analysis to perform mathematical functions on data after it is acquired. This analysis consists of
computing of basic statistics of the measured parameters and advanced functions. Offline
analysis is integrated with data logging applications. It is combined with generation of report,
historical display and also sharing of data functions. The data logging applications need to
display and view of measurements which are recorded. It is displayed into two types: historical
data and live data that are previously as well as currently acquired.
CE 3.3.4 Identified issues and their solutions
CE 3.3.4.1 Issues
I had faced issues regarding data security of the environmental data such as voltage,
temperature, flow, current, power, pressure and resistance. As WSN is handled of larger amount
of raw data that contains of secured information are not secured when it is used by unauthorized
person. The data are not protected and it is operated to have insufficient authorization over the
environmental data.

CE 3.3.4.2 Solution
I had used of security system that can able to set up user authorization protocol as well as
grant access to handle the environmental data and database. As the data contains confidential
information, therefore they should be kept password protected and away from unauthorized use.
CE 3.3.5 Plan to produce creative and innovative work
With the use of modern computers as well as sophisticated digital signal processing
methods, it provides an innovative solution to obtain and also organize of vast amount of
numerical data. It is proper to associate binary or digital to the definition of the numerical data.
Data implies binary as well as machine readable presentation of the information. The main
feature of concern is efficient as well as controlled management of the vast amount of the data.
Some of the data are secured, classified, highly critical, confidential, unsecured as well as
processed. It becomes imperative that the control system is used to manage varied data
effectively. The control system acquires data; extract the required blocks of the information by
means of it. It processed and derived to store data into storage system for the future references. It
leads to evolve of data logging system. Within the PC based data logging system, data
acquisition is accomplished by measuring the hardware such as sensor, signal connectivity and
conditioning.
CE 3.3.6 Collaborative work
I had prepared the project report on right time. My main focus is to complete the entire
project work on time as well as budget. I had sent the draft of the project report to the project
supervisor so that I can get the feedback so that on time I can able to conduct any type of
