1.1 Project Overview
1.2 Objectives of Project
The specific objectives of this project are to:
1. Monitor the actual parameters of clean room environment. 2. Alerts the conditions that exceeding classification.
The first objective is to monitor and analyze the actual parameter of cleanroom environment. By using DHT 11 (temperature & humidity sensor) and air contaminant sensor environment inside the cleanroom can be monitor and will be display out on the TFT LCD color display. The he data of the temperature, humidity, dew points and dust can be monitor and analyze every hour by the employee. The reasons why the cleanroom should be monitor is to verify either the process environment is perform according to the requires specifications because this areas are built to the specific requirements of the product that to be built.
1.3 Problem Statement
The purpose of this project is to monitor the quality of environment in clean room area where the products are manufactured which the concentration of airborne particles is controlled to the specified limits. The contaminants inside the clean room are produced by the people, process, facilities and equipment.
The way to control the contamination is by control the overall environment inside that area where temperature, humidity, dew points,light intensity and dust need to be tightly controlled. In this project, it will show the current value of temperature, humidity, dew points, dust and light intensity.
1.4 Scopes of Work
The scopes of works in this project are:
1. The design of this CPMS is to minimal the device for portable user inside the clean room area.
2. The implemented of CPMS will consists of totally 3 sensor in 1 device which are humidity and temperature sensor, air contaminant sensor , dew points and light intensity sensor.
3. The coding software that will be used for this project is Arduino.
1.5 Project Planning
1.6 Thesis Outline
This thesis report contains 5 chapters that will explain more details on each chapter to give an understanding about the whole project.
Chapter one will explain detail on the introduction of this project. In this chapter, it presents an overview of quality environment for the cleanroom, objective project, scope of works and project planning.
Chapter two will covers more about the literature review on the software and hardware that will be used in this project. This chapter will discuss about the source and article that related to this project. It will also relate the theory of components and programming language by using Arduino Uno Rev.3. So this is important to understand more about the overall concepts.
Chapter three will explain more about the project methodology, project planning and project finishing. It will show the progress of this project according to the due date which had been set before the project is in progress. In this chapter also will include the flow chart and block diagram that will explain more about the project system and it will also include Gantt chart for Semester I and II.
Chapter four is about the result and discussion for final year project. In this chapter it will show how to set up the arduino software connect with Windows and installation of arduino libraries. Other than that, this chapter will discuss about how to troubleshoot the problems if anything happen to the software and hardware.

Figure 2.3: DHT 11 Sensor
DHT 11 is the sensor used for this project. This sensor will display the current parameters for temperature, humidity and dew points where the sensor complex are calibrated with digital signal output. To ensures high reliability and long term stability, this sensor is using exclusive digital signal acquisition technique and sensing technology. It consists of resistive type humidity measurement component and NTC temperature component. This sensors is connected with high performance of 8 bit microcontroller that offering excellent quality, cost effectiveness, fast response and anti interference ability.
