WEEK 7 (FYP 2)

TITLE : CONSTRUCT THE COMPONENT

Activity :

In this week, i decided to construct/connect the component to another since i have done schematic design in last week. the connection will be refer to the schematic design. In this process, i will identified the quality of component whether broken or not. 

Objective:

• To connect all component in one circuit
• To  identify the broken component

Content :

Conclusion :

in conclusion, the objective is achieved. i identified that the relay is no functioning. after that i decided to buy new one. 

WEEK 6 (FYP 2)

TITLE : REDEFINE THE BLOCK DIAGRAM

Activity :The block diagram has to be redefine to give clearer view of the overall functionality of the system. Schematic design also done in this week. 

Objective :

To identify overall system of the project.

To identify connection between component.

Content: 

Block Diagram

After the some component was changed and added which is nodemcu and relay, i decided to change the block diagram. the new block diagram is shown in picture above. 

From the block diagram above, the prototype will work when there is signal detected by the sensor. The signal detected in this project is the gas leakage, smoke, or fire at the industry. After the sensor detects the fire or gas leakage beyond safe level, the data will send to Nodemcu microcontroller. Nodemcu microcontroller instantly turn on the prevention system. Exhaust fan will turn on when gas is detected so the gases are sent out to open air, when fire are detected, Nodemcu microcontroller will activate water sprinkler and The Esp8266 which is already built-in on Nodemcu will sends notifications to alert users through mobile apps which are Blynk app.

Schematic Diagram

The MQ-2 sensor which is the gas sensor is connected to analog input of the nodemcu microcontroller. The flame sensor is connected to digital input of the nodemcu microcontroller. If fire is appeared, it will sense the fire and send to nodemcu microcontroller. It will connected to the 2 channel relay module. 2 channel relay module is required for this project. It can control the output. Which means when the gas or fire detect, the relay module will triggered what output should turn on whether water pump or fan. The relay module will connected to digital output of the nodemcu microcontroller. 

Conclusion:

This can conclude that the updated block diagram is done and ready to be used on the poster later on an industrial day for presentation

WEEK 5 (FYP 2)

TITLE : FYP 2 BRIEFING

Activity :

On this week, i have attend the workshop briefing and also update my fyp report on chapter 3 which is methodology. It was a busy week but i managed to encounter the busy in successful ways.

Content :

1) Workshop Briefing 

     This workshop is held at :

     a) Location - TTL 2

     b) Date - 6/3/2019

     c) Time - 3pm - 5pm

     d) Co-ordinator - Dr.Marwangi and Dr. Imran

In this workshop, Dr.Marwangi has teach us how to do the :-

 a) Results & Discussion (Chapter 4)\

 b) Conclusion (Chapter 5)

 c) Abstract in Thesis Writing

Conlusion :

All this week task has been run smoothly and the report also has been update for chapter 3 on component list. The workshop briefing also has been attend and get some input to the report later.

WEEK 4 (FYP 2)

TITLE : CHANGE COMPONENT

Activity :

Last week, i bought some component. This week the progress of making prototype is began. After several try and error, I decided to change and add some component. 

Content:

List of new component :

• Nodemcu 
• Relay 2 Channel

NODEMCU

Nodemcu is used in this project as a main brain for the system. It controls the whole process of the system. The Nodemcu is a platform to Internet of Things projects. It is an open source. The nodemcu is includes the firmware which is built-in WIFI EP8266 so it can be connected to internet network. The Nodemcu is provided with the sets of analog and digital input and output. It contains 14 digital ports and only 1 analog ports. The input power is connected to USB port by USB cable. The Nodemcu can be programmed by the computer software which is Arduino IDE (Integrated Development Environment) through a type-B USB cable.

RELAY 2 CHANNEL

A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. Controlling a relay module with the Arduino is as simple as controlling any other output as we’ll see later on. This relay module has two channels (those blue cubes). There are other models with one, four and eight channels. This module should be powered with 5V, which is appropriate to use with an Arduino. There are other relay modules that are powered using 3.3V, which is ideal for ESP32, ESP8266, and other microcontroller

Conclusion:
The reason of changing the main component from Arduino to Nodemcu is the arduino is hard combine code with wifi module code. After done research and study new component which is nodemcu, it is more easy from the arduino because the nodemcu has built in wifi module (ESP8266) inside the component.
