Meeting with Supervisor
In this weeks meeting with Tn Hj.Dr. Zainuddin, we went through the project plan i created the week previous. The project plan included the features of sensor which I wanted to include in the project and ideas about each and how i would design it. In our last discussion i agree with Sir Zainuddin idea to apply the Taguchi gas sensor in my project due to it is the good sensor
Estimating the Budget
This week i not have many class due to the public holiday. so, my friend and i went to the Jalan Pasar to survey the price of the component, estimating the exact budget for my incoming final year project and to complete the proposal report that i need to submit to my supervisor . From my surveillance,the price is reasonable and still put on my budget. Alhamdulillah, my plan will going smoothly insyaALLAH.

Objective of this project
Air pollution is when the introduction of
chemicals, particulate matter or biological materials starts to contaminate the
air where it may cause harm and discomfort to human being and other living
organisms. It also damages the natural environment and the atmosphere. The
World Health Organization (W.H.O) stated that 2.4 million people died each year
directly attributed by air pollution, with 1.5 million of these deaths was
attributable by indoor air pollution. The Air Quality Index (AQI) which also
known as the Air Pollution Index (API) or Pollutant Standard Index (PSI) is a
number used by many government agencies to characterize the quality of the air
at a given location. As the AQI increases, an increasingly large percentage of
the population is likely to experience the increases of severe adverse health
effects
Because of that, this project intends to produce new air quality monitoring system that is user-friendly
in monitoring air quality continuously and efficient in prevent air pollution
also reduce hazard cause of the air pollution and
- To create new device and systems that cans automatic function so that air pollution can be monitoring time by time.
- To reduce the size of air monitoring pollution to make it as a portable unit and can be put in tiny space.
- To develop device that friendly user by give short-term warning of pollution risk to give early warning to people can make early preparation.
- To development of air quality monitoring system’s reliability estimate techniques by considering the failure and repair rate of the air monitoring component.

About Development of Air Quality monitoring System
For the first idea this project is about the development of automated monitoring device for environmental air pollutant detection. The main part of the device will consists of a detector, microcontroller and timer circuit. The gas sensor will be used to detect air contaminant level, in which the detection through the sensor measures in unit of part per million (ppm). A PIC Microcontroller will be utilized to convert the analogue signal from the sensor into digital signal which finally displays the result through the liquid crystal display (LCD)
