INTRODUCTION

Motorised Laundry System

Nowadays, it is hard to keep track on the progress of our laundry that we kept on drying outside in the daylight. But, little did we know that the weather is not going to be sunny all the time because rains and heavy storm might come along in the way when we want to do our laundry.

Hence, we have created a Motorised Laundry System to prevent the laundry from getting ruined by the rain when we cannot collect it because of the weather is raining heavily or so. Besides, it eases our burden of having to carry the laundry there and then by just simplifying it with a single switch to do all the work for us.

The system works by pressing the switch to move the laundry outside and pressing it again to move the laundry back inside the area where there is a roof covering the laundry from rains.

This is a simple project from us using a PIC16F877A .This tools function when the user presses a button and dc motor serves to pull the clothes into the home area covered by the aid of the conveyor belt.This will make the user ease when the rain come and we just push the button to pull the clothes into the home area.

                                   SITI SHUHADA BINTI JEFRIDIN (01DIS15F1028)

SYNOPSIS :

The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container.

The sensing is done by using a set of three probes which are placed at three different levels on the tank walls (with probe 3 to probe 1 placed in increasing order of height, common probe (i.e. a supply carrying probe) is placed at the base of the tank). 

In this project we show the water level indicator using three transistors which conducts as level rises, a buzzer is also added which will automatically start as the water level becomes full, auto buzzer start with the help of microcontroller. With the help of this project we not only show the level of water on seven segment display but also indicate the water full condition using a buzzer.

a) list of hardware and software

hardware : 1. buzzer 
                  2. 7segment common cathode
                  3. transistor (BC547) 
                  4. resistor (270k, 100r, 470r) 
                  5. wire jumper
                  6. PIC16F877A

 software : 1. MPLAB IDE v8.83 
                   2. Proteus 8 Professional

b) Circuit diagram for this project 

• when the container is empty, the output at 7segment is "E".

• when water is medium, the output at 7segment is "C" and buzzer sound with delay 500ms.

• when water is full, the output at 7segment is "F" and buzzer sound non stop.

e) Conclusion

1. Easy installation.
2. Low maintenance.
3. Compact elegant design.
4. The Automatic water level controller ensures no overflows or dry running of pump there by saves electricity and water.
5. Avoid seepage of roofs and walls due to overflowing tanks.
6. Fully automatic, saves man power.
7. Consume very little energy, ideal for continuous operation.
8. Automatic water level controller provides you the flexibility to decide for yourself the water levels for operations of pump set.
9. Shows clear indication of water levels in the overhead tank.

Conclusion

This project can make the guest to know what to do when come to the house. This project also enable us to gain experience in electronic circuit and designing. However, a lot of difficulties were encountered in the process of realizing the project work like putting the components correctly in the board and detecting some errors.
