Professional Practice Week 1 contributes 30% to your final module mark and
assesses learning outcomes 1, 3 and 4.
This assessment is taking place as a Professional Practice Half Week.
Important Information
You are required to submit your work within the bounds of the University Infringement of
Assessment Regulations (see the Programme Handbook). Plagiarism, paraphrasing and
downloading large amounts of information from external sources, will not be tolerated and
will be dealt with severely. Although you should make full use of any source material, which
would normally be an occasional sentence and/or paragraph (referenced) followed by your
own critical analysis/evaluation. You will receive no marks for work that is not your own.
Your work may be subject to checks for originality which can include use of an electronic
plagiarism detection service. Where you are asked to submit an individual piece of work, the
work must be entirely your own. The safety of your assessments is your responsibility. You
must not permit another student access to your work. Where referencing is required, unless
otherwise stated, the Harvard referencing system must be used (see the Programme
Handbook).

Scenario
Rationale
You are currently working for a software development company who provide IoT system
solutions to small and medium sized technology companies in the food, hygiene and biomedical
sectors.
Currently you are working on a contract that requires a proof of concept prototype to monitor
environmental conditions during access to a controlled bio-medical manufacturing area. This
controlled area is normally sealed and kept under steady state conditions. However, it is
sometimes required to access this area for very short time periods to perform upkeep and
maintenance tasks whilst the manufacturing process continues.
The contract calls for you to provide a prototype software simulated IoT solution aimed at
logging environmental conditions during these access periods. In addition, you are to
provide a console based desktop application that will allow basic visualisation and analysis
of the logged data from the simulated IoT system.
Tasks - Software Simulated IoT Prototype System – You need to provide a suitable
software simulated IoT prototype rig (using software simulated MCUs, sensors, input
devices, output devices etc) that will allow the temperature and relative humidity to
be recorded and then logged during an access period to the controlled area. In this
prototype system, you will be simulating the actual access period to the controlled
area (obviously, as you do not have the manufacturing facility available to you).
You must provide the following functionality, with updates in your program happening
approximately once every second:-
a. A recorded log of the current temperature (in Celsius) and relative humidity (in %),
this must only be recorded and logged during an access period.
b. A date and time timestamp of each set of readings from a. above as they are
recorded in the log.
c. If the currently active access period has lasted around 10 seconds or less then
show a green coloured indicator light.
d. If the currently active access period has exceeded 10 seconds then show a red
coloured indicator light.
e. If there is no currently active access period then no coloured lights should be
showing.
f. A visual output of the current date, time, temperature and relative humidity
readings whether there is a currently active access period or not.
Page 3 of 5
g. A visual output of the approximate number of seconds a currently active access
period has lasted.
When providing the above functionality make sure you only record and log readings
during active access period, not outside of these. In order to properly prototype your
system you will have to provide a way to simulate these access periods. You will also
need to provide a way to gracefully stop and shut down the run of your prototype.
You can assume the date and time for all your readings begins at 12th May 2021
(which is a Wednesday), 9:30am, 0 seconds and 0 microseconds.
As this is a simulation, you can record readings that are somewhat manipulated from
the environmental sensor so you can see and test the operation of the prototype.
Such simulated data can then be observed when utilising it in the desktop application
detailed below. - Desktop Application – Using the recorded and logged data taken from a run of the
prototype IoT system, you need to provide a console based desktop application that
provides the following output for each access period logged in the data:-
a. Start date and time of the access period.
b. End date and time of the access period.
c. Approximate number of seconds the access period lasted.
d. A list of all the recorded readings (including the timestamp for each) during the
access period
As stated, this output is required to be purely textual, displayed in a console terminal
and does not need to be output in a graphical format. The individual elements of the
output can be in any order but it must be obvious for which access period each set of
data is associated.
Note: You can adapt tutorial example code and sample solution code to help
you in solving both of these tasks detailed above.
Deliverables - Python 3 script(s) that provide the functionality detailed in Task 1 (Software
Simulated IoT Prototype System) above. This Python 3 script(s) should be
properly structured and commented to ensure good quality and describe how
each element of the script operates in providing the solution. - A detailed guide (word processed and provided as a Microsoft Word document)
as to how the required simulated IoT rig is to be prototyped, how the Python 3
scripts are to be run and how to retrieve the logged readings from the simulated
monitoring device after a run of your prototype program has finished.
The emphasis here is on detailed. Assume that the user of this guide does have
the same CET235 simulated prototype rig software available you had available
during the teaching sessions on the CET235 module. Use diagrams, screen shots
Page 4 of 5
etc. to support your guide so that it is obvious how to operate your software
simulated prototype rig solution, how to run your Python 3 script(s) and how to
retrieve your logged readings. - Python 3 script that provides the functionality detailed in Task 2 above. This script
should be properly structured and commented to ensure good quality and
describe how each element of the script operates in providing the solution. - A detailed guide (word processed and provided as a Microsoft Word document)
as to how to run your desktop application, in particular describing how to get the
logged readings from the software simulated IoT system into the desktop
application for visualisation and analysis. In addition, provide a set of screen shots
and descriptions of these screen shots explaining what is being output in your
application so that the user can understand what they are seeing.
Submit all these scripts and documents as a single zipped archive file to the Canvas
Assignment Page for this assessment by the deadline 5PM, FRIDAY 14th MAY 2021.
