Design And Construction Of Automatic Cloth Retrieval System
Overview
ABSTRACT
For a working couple, it is hard to find time to have laundry day where the cloth is dried through the whole day because the weather can change from sunny to rainy days. This project will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day. This project uses Microcontroller PIC 16F877 to install all program that will give instructions to conduct this system properly. This part needs DC motor to convert electrical power into mechanical power for retrieve-out and retrieve-in all the clothes. Temperature sensors that will be use in this project can measure temperature and day condition whether it is sunny or rainy day more accurately. LDR (Light Dependent Resistor) sensors will be used to detect light. Rain detector also will be use to sense when it begins to rain outside by detecting rain water from moisture impedance sensor locate at the rod. The dry-time of the clothes will be setup using rotary knob switch and it will automatically retrieve-in the clothes using DC motor when the dried-time is finished. This project will be display the day condition, temperature and dry-timer using LCD (Liquid Crystal Display) or indicator light such as LED (Light Emitting Diode).

1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
People are now-a-days working in corporate companies or organizations such as banking and uniform work (like police and military), where they go for work in morning and come only at night they wash clothes in machines and they suspend it in open terrace and they are unable to lift the suspension of clothing during the day rain. For people who working, they don’t have to worry about their clothes that have been dried outside. People often don’t have time to manage their routine. This project is developed for working couple, it is hard to find time to have laundry day where the cloth is dried through the whole day because the weather can change from sunny to rainy days. This projects use Microcontroller PIC 16F877 to install all program that will give instructions to conduct this system properly and will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day. This part needs DC motor to convert electrical power into mechanical power for retrieve-out and retrieve-in all the clothes. Temperature sensors that use in this project can measure temperature and day condition whether it is sunny or rainy day more accurately. LDR (Light Dependent Resistor) sensors use to detect light. Rain detector use to sense whether it rain or not at outside by detecting rain water from impedance sensor locate at the rod. The dry-time of the clothes will be setup using push button and it will automatically retrieve- in the clothes using DC motor when the dried-time is finished. For status display, this project will be display the day condition, temperature and dry-timer using LCD (Liquid Crystal Display) or indicator lights such as LED (Light Emitting Diode)
1.2 PROBLEM STATEMENT
People often forget to lift the suspension of clothing during the day rain which exposes their clothes to rain which makes their clothes to take longer time to dry. Most especially people who are working or doing business, they don’t worry about their clothes that have been dried outside. This device brings solution to this problem. This project develop for working couple, it is hard to find time to have laundry day where the cloth is dried through the whole day because the weather can change from sunny to rainy days. This projects use Microcontroller PIC 16F877 to install all program that will give instructions to conduct this system properly and will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day.
1.3 AIM OF THE STUDY
The aim of this work is to design an electro-mechanical device that will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day.
1.4 PROJECT OBJECTIVE
The main objective of done this project is to develop an automatic system for cloth retriever within required range and specific objectives of this project are listed as followed:
- It will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy This project is done by developing the circuit of Light Dependent Resistor which is could detect the sunny day and rain detector circuit to detect whether it is rainy day and programming the controller to control the motor to retrieve-out the clothes when it is sunny day and retrieve-in the cloth when it is rainy day.
- The dry-time of the clothes will be counted and it will automatically retrieve-in the clothes when the dried-time is finished. The dry-timer was set by user whether 3 hours, 4 hours or 5
- This project will be display the day condition, temperature and dry-timer. Day conditions will display sunny, cloud or
It depends on the current
- Temperature range that has been set by programming. Also, could display dry timer that has been set by
1.5 SCOPE OF THE PROJECT
This device uses Microcontroller PIC 16F877 which is used to install all program that will give instructions to conduct this system properly and will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day. This work also needs DC motor to convert electrical power into mechanical power for retrieve-out and retrieve-in all the clothes. Temperature sensors that use in this project can measure temperature and day condition whether it is sunny or rainy day more accurately. LDR (Light Dependent Resistor) sensors use to detect light. Rain detector use to sense whether it rain or not at outside by detecting rain water from impedance sensor locate at the rod. The dry-time of the clothes will be setup using push button and it will automatically retrieve-in the clothes using DC motor when the dried-time is finished. For status display, this project will be display the day condition, temperature and dry-timer using LCD (Liquid Crystal Display) or indicator lights such as LED (Light Emitting Diode).
1.6 SIGNIFICANCE OF THE STUDY
The main advantage we can mention is time saving. The device will reduce our work and save our time. It is compatible with climate changes as the sensors are used, the device can easily recognize the climate changes.
As the device is simple it can be used by any kind of user. This prototype is less expensive. People often don’t have to change their routine. This project is useful for working couple, who don’t find time to have laundry day where the cloth is dried through the whole day because the weather can change from sunny to rainy days.
1.7 DEFINITION OF TERMS
The following terms are defined conceptually or operationally for better understanding of the study:
Clothesline: A piece of rope or a wire that people hang wet clothes on to dry.
Rain Sensor: A switching device activated by rainfall, it is an improvised water sensor made of PCB which is designed to close the circuit when the rain falls.
Sensitivity: The ability of the rain sensor to sense different amount of rainfall.
DC Motor: An electrical machine that converts electrical energy to mechanical energy, this refers to a dc motor that rotates the shaft and leads to pull the clothesline inwards and push outward.
Control Circuit: A switch (or a group of switches) and a motor. This refers to the (auxiliary) circuit of the magnetic contactor that will control the rotation of the motor and the time that it will run and stop.
