FYP2 WEEK 11

Title: Final briefing of FYP 2

Objective: 

• to be brief on the project demonstration
• to be brief on the full report compilation
• 
  

Activity:

In this briefing, student briefed on the objective stated earlier. The talk focusing on how students need to professionally present and demonstrate their prototype during the Industrial day. Few tips are given which are dressing code, training to talk in front of mirror and etc. Apart from that, students are also briefed on how to complete their full report of their FYP 2. Some tips are also given and the template of the report are given via link from the fyp website. The template given are used to print the report in hardcover. Students are required to follow exactly to the template in order to avoid any error in the formatting and others problem.

After the briefing, students are dismissed. The student continues to preparing and testing their prototype for the industry day ahead.

FYP2 WEEK 10

Activity: Sketch the house model

Objective: 

• To sketch the house model for the prototype using SketchUp software

A house model was made out for the prototype's testing run. Inside the home, the temperature sensor and heating pad were installed. A water pump controlled the sprinkler system on the roof, which sprayed water through tubing going from a water tank, which was then re-circulated into the sprinkler system. A fan was installed under the roof to blow the cool air into the house.

FYP2 WEEK 5

 Activity: START BUYING THE COMPONENT

Objective: Starting this week, the student already listed the component that needs to buy. For most of the component such as resistor, transistor, potentiometer etc. I bought from Shoppe. The component will take some time to be delivered. For the time being, I completed my full circuit diagram for the simulation.

FYP2 WEEK 4

 Activity: UPDATE THE BLOCK DIAGRAM

Objective: 
To identify the overall system of the prototype.

The temperature sensor will be the main input for my project. The temperature sensor will read the ambient temperature and the temperature will be shown on the LCD 20x4. The Arduino Uno R3 then processed the analog input signal converted into a digital output. The main output for this project would be the fan, the water pump, and the heater. The sprinkler system is basically a water distribution piping where it enables the water to flow to the roof top.

FYP 2 WEEK 3

Activity: FIRST FYP 2 BRIEFING

Objective:

To be brief about FYP handbook, Project Development, Progress Report, Final Report, Attendance, Assessment forms.

1. Students need to update the logbook/blog regularly
2. The student must meet supervisor for consultation
3. Attendance that below than 80% will be bared.

FYP 2 WEEK 2

 Activity: STUDY ON ARDUINO MODULE

The student continues to collect additional data on the module that needs to be used in the second week of the FYP 2. The data enables the student to have a better understanding of the module's behavior. The student may then plan which module will be utilized to create the prototype based on this information.

FYP 2 WEEK 1

Activity:

The first week of Final Year Project 2 has begun, the first thing that need to be done is to continue progress report that had been done earlier previous semester.

Objective:

• To plan and organize the 17 weeks for Final Year Project 2.
• To continue the progress report which is done earlier in previous semester for Final Year Project 1.
• To complete this semester accordingly as planned.

Content/ Procedure:

Previous Final Year Project 1 Content/ Progress Report: -

• Chapter 1: Introduction
• Chapter 2: Literature Review
• Chapter 3: Methodology

Conclusions:

The Development of Automatic Cooling Roof System for Building Temperature Efficiency had officially began. Chapter 3: Methodology in Progress Report will be constructed again.

FYP1 WEEK 16

 Activity: Proposal Report Compilation and Correction

After I compiled my report, I submit it to Dr. Zuhanis for the plagiarism check. Turn out that my plagiarism result is 40%. So I need to reduce it to less then 20% (<20%). Then I made some correction using the plagiarism result report as reference. After I have done with my correction, I resubmit my new FYP 1 Report to Dr. Zuhanis to do the plagiarism check and my plagiarism result is 10%.  

FYP1 WEEK 15

 Activity: Proposal Report Compilation and Correction

For this week, I just focus on Chapter 3 which is the methodology of my project like block diagram, circuit diagram and flow chart. I have done some research about the related article that I want to use as references. The writing continued as usually.
