ABSTRACT

This work is on an automatic rain water sensing window. This device was built to protect the interior of houses as it works automatically by sensing the water. It is particularly very helpful device to use in rainy season. The concept of sensing rain water to close the window is not new. It has been developed to use in the automobile sector. But this invention can be use successfully for domestic purpose. This system can evaluate whether the water particles are contracting with the window or not and sensing this it will close automatically to protect the interior of the house.

CHAPTER ONE

1.0                                                        INTRODUCTION

1.1                                           BACKGROUND OF THE STUDY

Nowadays, technology has make life easier and comfortable. Those equipments are related with different engineering field (e.g. electrical, mechanical etc.) In order to protect the household in rainy season, this device has been developed. The field of this work is mechatronics, which is a combination of mechanical and electronics has had great advancement in the past few years. Mechatronics is implementing in this development to construct an automatic controlled commercial window. Hashim et al. [1] tried to develop a new wiper system to wipe rain water from vehicle’s windscreen. In older system, wiper was used to control manually and the process of pulling up the wiper was quite difficult. So, objective of their work was to modify the system by providing automatic wiping system. They developed an automatic control system by using a Peripheral interface controller and water sensor. Their system could manage to achieve the aim as it could remove rain water automatically from outside the car. The rain sensing automatic power window has a rain sensor, a motor operating circuit, a pair of motors and a driver mechanism for sliding type windows. Powered by 12V DC power from a transformer, motors have enough torque to move the windows back and forth as required. When rain falls on the sensor, it sends signals to the circuit. The microcontroller is programmed which acts as a relay for the circuit that sends signal to the motor driver which gives power to the motors. The windows are sliding windows with smooth bearings to reduce drag and friction for proper sliding movement.

The aim of this project was to build a rain sensing automatic window mechanism for house hold. This project has been done derived for introducing automatic rain sensing windows of luxury cars and has been modified for application in commercial house window. The same principle works for both

1.2                                                  PROBLEM STATEMENT

Traditionally, window of a building or house is operated by the occupant whenever it is raining; this calls for an attention and involves labour. This invention came to solve this problem which automatically closes a window whenever rain drops on the sensor.

1.3                                             OBJECTIVE OF THE PROJECT

This objective of this work is to build a rain controlled automatic window open and close device that automatically closes a window during the time of rainfall and vice-versa.

1.4                                       APPLICATIONS OF THE PROJECT

Apart from using this device at home, this device can also be used in the following places:

  1. It is used in four wheeler
  2. It is used in aircraft
  3. It is used in train
  4. It is used in six wheeler

1.5                                         SIGNIFICANCE OF THE PROJECT

This system reduces cumbersome closing and opening operation and improves occupant’s level of comfort.. Other significance includes:

  1. Low cost automation project.
  2. Free from wear adjustment.
  • Less power consumption.
  1. Operating principle is very easy Installation is simple.
  2. It is possible to operate manually/automatically by providing On/Off switch

Sensor cost is very low due to the use of conductive sensor.
1.6                                    LIMITATION OF THE PROJECT

Additional cost is required incase optical sensor is used. This system applied in the case of water falling on the window only.

1.7                                                        METHODOLOGY

To achieve the aim and objectives of this work, the following are the steps involved:

  1. Study of the previous work on the project so as to improve it efficiency.
  2. Draw a block diagram.
  • Test for continuity of components and devices,
  1. Design and calculation for the device was carried out.
  2. Studying of various component used in circuit.
  3. Construction of the circuit was carried out.
  • Finally, the whole device was cased and final test was carried out.

1.8                                                         PROJECT ORGANISATION

The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
