*14 Week : Presentation

This week is a week of PSM1 Presentation. The main thing that have to complete is Slide Show for the presentation. The purpose of this presentation is to let the panel know what is the project or product that will be produce, and either we know and understand how we gonna do it. So it is important to understand all the detail of the project and do a research about the all the component and the method uses. There is my complete slide presentation. The max time of the presentation is 10min, and another 5min for the Q&A session.

*13 Week : REPORT PSM 1

This week is the last week before the presentation week, so there are so many things that had to be complete by this week. Such as;


#Literature review : The related work
There is some related work to my Air Quality Monitoring. The function of all this work is same, which is to monitor the air, but in different method.

Temporal Air Quality Monitoring Using Surveillance Camera
The aim of this work is to develop a state-of-art reliable technique to use surveillanc camera for monitoring the temporal patterns of PM10 concentrations in the air. In this work an internet protocol (IP) network camera was used as an air quality monitoring sensor. The figure below show the IP network camera and the overview of Temporal Air Quality Monitoring.



Hierarchical Air Quality Monitoring System Design
The aims of this work is to build the prototype system by hierarchically deploying terminal sensor nodes inside the smart buildings of each floor and data collection units and routers in the open spaces between smarrt buildings, and transferring the sensor thing data back to the information processsing center for real-time information. The information processing center is through ZigBee wireless protocol. The detection of air is by CO, SO2, NO, NO2 and PM2.5 sensors. The figure show the  MQ135 sensor 2.5 sensor.




Air Quality Monitoring Using Remote Sensing and GIS Technologies
This is the new method, which is integrates satellite remote sensing and Geographical Information System (GIS). It can be used to continually monitor air quality at micro-scale level.


I had study this three related work, there are the comparison between this three and my project.

#Literature Review: Competitive Analysis
Competitive Analysis is the product that already in the world market with the same function of my project, to monitor the quality of air.

Air Mentor
DC1100 Air Quality Monitor By Dylos
Airassure PM2.5 Indoor Air Quality Monitor
Air mentor is a product from China. The founder of this product is CoAsia Microelectronics Corp. The purpose of Air Mentor is to monitor the concentrations of VOC, particulate matter, temperature and relative humidity. This product are indoor air monitoring, cannot use it outside of the building.
The founder of DC1100 Air Quality Monitor is Dylos Corporation. DC1100 features technology and engineering that allows monitoring of indoor air quality with an LCD screen that provides small and large particle counts with a dynamic bar graph showing actual count reading. Multiple modes including minute, hour, day and monitor to evaluate your air quality and store up to 30 days of air quality history for review.

This item is produce from TSI, the world pioneer in molecule estimations, the AirAssure PM2.5 Indoor Air Quality (IAQ) Monitor can give continuous, dependably exact estimation of indoor PM2.5 dust focuses, one of the best wellbeing dangers today. The AirAssure Monitor is the savvy on-the-divider instrument to address the issues of all the partners in a building.


I had search and study about this three product, and the table below show the comparison of all this product and my project.

From the table, show the comparison between the element of Sensor, Communication, Location and price. The biggest different between all this element is the price. The product out there is very high in cost. That why my project will attract people to have it when it in the market. InsyaAllah :D

*12 WEEK : Title of Project / Panel for presentation

#The Official Title of Project
On this week, my SV had decided the official title of my project, which is
DEVELOPMENT OF LOW-COST AIR QUALITY MONITORING SYSTEM.
Besides that, for this week also, i knew the panel for my project presentation PSM1, which is Madam Izadora Binti Mustafa as a Panel 1 and Madam Raeihah Binti Mohd Zain as Panel 2 .

As mention on my official title of project, the most important element of my project is LOW COST. So, i had to make sure that the device or product that i will produce is low cost compare to other product in market.

For this week, i had checking my report for this PSM1. There is a lot of mistake. For example, the arrangement of content. It should be from general info to specific info about my project.


#123dCircuits
Besides that, on this week, my SV had introduced the online software for circuit simulation, which is AUTODESK 123dCIRCUITS. This software allow you to do the circuit simulation. By this application, we can share the our simulation with others user and can look for the other simulation as a references. This is the link of 123dCircuits https://123d.circuits.io/
I had done a simple simulation by this software. I had refer to other work. There is the example of 123dcircuits simulation.


This circuit is one of my try to use this software. i had used potentionmeter to vary the temperature sensor.




*11 WEEK : INDOOR & OUTDOOR & PORTABLE / WIFI SHIELD

#Indoor & Outdoor & Portable
Today, i will reported about my progress on Week 9th. For this week, i had discuss w my sv about the workscope or the limitation of my project, i had confirm about the characteristics of my project, which is, my project can be used indoor and outdoor. The most important thing is, it is not exposed to wet surface. Next, my project is portable device. This project is mild and small, so it will be easy to user to bring itt everywhere. In addition this device is using battery, does not need external supply.



#Wifi-Shield
From the previous post, i had mention that i had confirm to use Arduino Uno and Arduino Ethernet Shield for as a processor for my Air Quality Monitoring System. But, after some research and discussion with my SV, we had agree to change Arduino Ethernet Shield to Arduino Wi-Fi Sheild as the interface to connect my device to internet. The most reason why i change this Arduino is because, Arduino Wi-Fi Shield will directly connect my device into the internet. Compare to Ethernet Shield, this device need to be connected to the internet manually, which is the user need to connect the device by using their own Wi-Fi or internet connection.

What is Arduino Wi-Fi Shield ?
Arduino Wi-Fi Shield is another board in Arduino family. This board make the connection to Wi-Fi network simpler, no need the configuration in addition to the SSID and the password. This is th illustration of Arduino Wi-Fi Shield.

Features
Operating voltage both 3.3V and 5V
Connection via: IEEE 802.11 b/g/n for up to 72 Mbps networks
Encryption types: WEP and WPA2 Personal
Support TLS 1.1 (SHA256)
Connection with Arduino or Genuino on SPI port
On board Crypto Authentication by ATMEL


From all the characteristics of Arduino Wi-Fi Shield, it is very suitable for low-cost air quality monitoring system. This is because this project is using Wi-Fi as the main medium transmission. Besides that, Wi-Fi Shield is very easy to use with the Uno because Wi-Fi Shield is comes with an ‘easy to use library’ that allows Arduino Uno to connect to the internet with few instructions.
