Week 5 (FYP 2)

This week, I began to assemble my project on a Raspberry Pi computer instead of an Arduino microcontroller. 

Off the bat, the Raspberry Pi had some notable differences from Arduino as it didn't require a laptop or PC to program projects with as the Raspberry Pi is itself a computer that requires only a mouse, keyboard and monitor to begin programming projects with.

After re-programming all the sensors to collect data using the Raspberry Pi, it was found that only four of the sensors were capable of working with the Raspberry Pi. The Grove Air Quality Sensor was found to be incapable of working with a Raspberry Pi as the Raspberry Pi had no way of reading Analog inputs by itself.

Week 4 (FYP 2)

My progress this week was mostly comprised of me testing the sensors that have arrived. 

The PM 2.5 sensor, DHT22 temperature and humidity sensor, Grove Air Quality Sensor, and MQ-135 mixed-gas sensor were tested, and all were found to be fully functional, capable of collecting and displaying data via Arduino IDE's serial monitor and serial plotter.

It should be noted that for the MQ-135 sensor, it was recommended for it to be powered on with a 5V power supply continuously for more than 24 hours, as it needs some "burn-in" time for its sensor to adapt to clean atmospheric air before it can becomes sensitive towards harmful gases.

 

 

Also, the second batch of components for my project, those being the ones ordered from my.Element14, arrived this week.

Week 3 (FYP 2)

This week, the first batch of components arrived on my doorstep. They were the parts that were ordered from Cytron.io. 

As it contained an Arduino Mega and several of the sensors required for the project such as the PM 2.5, temperature and humidity, LIDAR etc.; I began to do some testing on the sensors to understand how they operate, even though in my thesis I'd be gathering data and results using a Raspberry Pi computer.

Week 2 (FYP 2)

After identifying all the parts and where to purchase them on the internet, I filled up UniKL BMI's Online Purchase Request Form with all the components for my project.

Afterwards, I sent the forms to Dr. Sabry for purchasing.

Week 1 (FYP 2)

This week marks the continuation of my Final Year Project for my Final Year Project, under the Final Year Project 2 (FYP 2) subject. 

Dr. Sabry requested that I begin listing up the components for my project, their price, and where to purchase them on the internet so that he can purchase them using the grant given to him by Multimedia University (MMU).

So, most of my progress this week was of me browsing online electronic component retailers such as Element14 and Cytron for the various sensors and components of my projects.
