Week 4: Flowchart

Title: Flowchart

Objective: To identify the overall system in this project.

Progress:
Flowchart process for circuit operation
The program starts when  MQ6 sensors check the concentration of the gas; the sensor will read the output voltage of the MQ-6 sensor. When the pin of the sensor is interrupted means the sensor detects beyond safe level so the output will be activated by turn on the buzzer, exhaust fan and the led to the users. The system always read the voltage interrupt pin and stop when the sensor voltage back to origin state.




Flowchart process for ESP8266 module operation

When the program on, the application Blynk will check the device either on or off, when the device is on, the ESP8266 will check the reading of gas. When the pin of the sensor is interrupted means the sensor detects beyond safe level so the output will be activated by sending the notification via application Blynk. When the device in turn off, the application Blynk sends the notification that the device is turned off.  

Conclusion: 
The use of this flowchart is to make sure the operation

week 12: Testing and Troubleshooting

Image
Title:  Testing and Troubleshooting Objective:  To test the functionality of my project Progress:                 Last week I tested the function of the Blynk application and the result as desired.  for this week, I need to test the functionality of my project installed in the prototype as shown in the figure below. The prototype of project There are no presences of gas leakage so that the display show “Gas normal” and the exhaust fan is in a turn off situation means the sensor did not receive any signal.  when the gas detected by the sensor. The MQ6 sensor sends data to Arduino and gives the high output to activate the exhaust fans, buzzer and display the “Gas alert” in the LCD display .  Conclusion:                     As the conclusion, by the end of this week, I finally manage to test the prototype and get the result as desire...

Week 11: Test the Functionality of the Blynk application

Image
Title: Test the functionality of the Blynk application Objective:  To test the functionality of the final year project. To send data from MQ6 sensor to Blynk application. Progress: First, connect supply to the Arduino. Put the hardware in the closed environment. Switch on hotspot from mobile phone to act as a Wi-Fi for the Wemos D1 to send the data into Blynk apps, and then open Blynk apps in the phone and monitor the data collected from the  sensor MQ6. when gas is detected, Blynk libraries will connect to Blynk server and pair up with any Smartphone. The push notification widgets notify the user by sending the alert message and the location of the incident occurred. Besides, it also sends notification via email. Conclusion:                     As the conclusion, by the end of this week, I finally understand the concept and operation of my project based on Blynk application.

Week 14: Final Year Project Presentation Day

Image
Title: Final Year Project Presentation Day Objective:  To present the poster and demonstrate the final year project.      Method: Present the poster and slide to the assessor, demonstrate the hardware project, answer questions and being evaluated by the assessor. Progress:  The Final Year Presentation  (FYP 2) took place in the Dewan Gemilang, Unikl British Malaysian Institute (BMI) on 2 May 2018. The presentation started at 8:30 in the morning. I was assigned to two assessors from the FYP committee who are lecturers from the Electrical Section.  Conclusion: Everything went well for the presentation. After the presentation is time to prepare the report
