CHAPTER 1

INTRODUCTION

Project Context

O Fans are widely used in industrial and commercial applications. From shop ventilation to material handling to boiler applications, fans are critical for process support and human health.

OThis project is entitled “Automatic Fan Speed Controlled by the Used of Temperature Sensor”.

OThe idea behind this work is to control the speed of a fan using microcontroller based on variation in temperature.

Statement of the Problem

OThe general problem of the study is how to develop an automatic fan based on temperature sensor, a system that would give solution to the alarming temperature abnormalities specifically for the benefit the students and faculty of the Bulacan Agricultural State College.

This project seeks to resolve the following problem:

1. What methods will be used in order to develop an automatic fan without further human intervention?

2. In what way can this automatic controlled fan be useful and convenient to the students and professors of BASC?

3. What are the benefits and advantages of this Automatic Controlled Fan in every student and professors of BASC?

Objectives of the Project

OThe general objective of the project is to develop and manage an automatic fan speed controlled by temperature sensor set by a user of the system for the classrooms and offices of the Bulacan Agricultural State College.

Specifically, the study aims to:

O develop a system that can control and monitor the speed of the fan based on the temperature sensor without human intervention;

O provide useful and convenient fan for students and professors of BASC;

O technologically build an automatic fan system that will help to maintain the good ambiance of the classrooms and offices in BASC;

Scope and Limitation of the Project

O The project entitled “Automatic Fan Speed Controlled by the Used of Temperature Sensor” can be used at home for the daily living when weather is not that comfortable for mankind.

O This can also be used in some electronic devices such as laptops, personal computers, and washing machines, exhaust fan in hotels, CD and DVD players.

OThis system will provide advancement of the daily activities of BASCinians, such as when having classes, meetings etc. in a given classroom.

OWith this system the usage of air conditioning unit could be lessened and energy could also be saved.

OThis project has also limitations such as it can only be maintained by a technical person. Thus, it becomes difficult to be maintained. Due to temperature variation, after sometimes its efficiency may decrease.

CHAPTER IIBACKGROUND OF THE CAPSTONE PROJECT

O In February 2011, an automatic occupancy and temperature control for ceiling fan operation was invented by Danny S. Parker and Kendall Ryan Johnston in University Of Central Florida, wherein the project was to control for tuning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate the speed of the fan.

METHODOLOGY

OIn this chapter, the developer shows the different diagrams and figures that will serve as a representation of the whole system.

OProgramming in VB.Net is a combination of visually arranging components or additional lines of code or more functionality.

OAs for the database, we will be using MySQL since it is the most convenient and easy to use in database development.

OThe Institute has four courses, Food Technology, Geodetic Engineering, Information Technology and Agricultural Engineering that has a total number of eighty-six students that will benefit in this study.

OThe Automatic Fan Speed Controlled by the Used of Temperature Sensor will be given to the company of the Institute of Engineering and Applied Technology with the helping hand of Mr. GM Villacorta.

Requirement Specification

OThe client asked the proponents to develop an Automatic Fan Speed Controlled by the Used of Temperature Sensor that will help people in conserving energy and time consumption with regards to manipulating the panel button of a fan.

OIt is also suggested that the degree certain in a fan could be reset regardless of the temperature has been set by the developer.

OThus, the fans can consume unnecessary power in unoccupied rooms.

O Another problem occurs when newly arriving occupants to new rooms and/or to darkened rooms have to search for hard to find wall toggle switches and/or overhanging chains to turn on the fans.

O Figure 2 shows the different actions that can be found in the system. The user will select for the temperature and time, after selecting the temperature and time it will be stored in the database. After the input of the temperature and time, the setting for the auto fan will take place. It is responsible for the automatic fan.
