AUTOMATIC PUMP CONTROL WITH WATER LEVEL MONITOR AND DIGITAL DISPLAY

The Automatic pump control with water-level monitor and digital display is an electrical system constructed for convenient and adequate control of water into overhead tanks (OHT). The device switches “ON” automatically when the water level falls below a certain level and automatically switches “OF” when help tank is filled up. This control function is however through the help of the widely available CD4066, bilateral switches CMOS IC to indicate the water level through the 7 segments display unit. The design ensures a reliable and efficient means of water control, a practical conservation of water and a high speed operation with the help of the electrical motor. It eliminates problems of water overflow by application in both domestic and industrial settings.

CHAPTER ONE

INTRODUCTION

1.0 BACKGROUND

The project “automatic pump control with water level monitor and digital display” is design to monitor the level of liquid in the tank. The system has an automatic pumping system attached to it so as to refill the tank once the liquid gets to the lower threshold, while offing the pump once the liquid gets to the higher threshold. Sustainability of available water resource in many reason of the word is now a dominant issue. This problem is quietly related to poor water allocation, inefficient use, and lack of adequate and integrated water management. Water is commonly used for agriculture, industry, and domestic consumption. Therefore, efficient use and water monitoring are potential constraint for home or office water management system. Moreover, the common method of level control for home appliance is simply to start the feed pump at a low level and allow it to run until a higher water level is reached in the water tank. This water level control, controls monitor and maintain the water level in the overhead tank and ensures the continuous flow of water round the clock without the stress of going to switch the pump ON or OFF thereby saving time, energy, water, and prevent the pump from overworking Besides this, liquid level control systems are widely used for monitoring of liquid levels in reservoirs, silos. Proper monitoring is needed to ensure water sustainability is actually being reached with disbursement linked to sensing and automation, such programmatic approach entails microcontroller based automated water level sensing and controlling or using 555 timer IC.

1.1 AIMS AND OBJECTIVES

The goal or objectives of which the designed device is expected to accomplish is to build an automatic water level control with automatic control system. In this project sensors are place at different level of the tank and with the aid of this sensors, the micro-controller monitor the level of the liquid at any particular point in time, some of the objectives are;

1.  To design an automatic water monitoring system

2.  To incorporate an interactive medium between the end user and the machine

3.  To prevent over labor of the pumping machine and prevent it from getting bad

4.  To avoid wastage of water

5.  Since the demand of electricity is very high, automatic water level control saves energy.

1.2 JUSTIFICATION

Automatic water level monitor came into existence because of human error and inconsistence that is associated with manually operated water pumping machine. This is because it takes time for individual who is manually operating the water pump to turn off the pumping machine and this may cause water spillage and at times the individual might not know that the water level has drop so low until the tank is completely empty. This was the problem that leads to the development of the ideal of an automatic water level control and automatic pump short down.

1.3 SCOPE OF THE PROJECT

The project was design to automatically control the pump which ensures constant reserve of water in the reservoir. The scope of the design was keep concise and simple to in other not to introduce unnecessary complexities and render it generally uncomfortable. The system does not have attached complex peripheral device which though impossible for the detail printable information has been excluded for reasons of affordability material of low range and less accurate performances as opposed to a well built automatic water pump was use d to achieve this aim, the automatic water level controller detect and control the water in the tank.

1.4 CONSTRAINS

The biggest setback experience during the course of this project is difficulties in finding the design of the project, secondly sourcing of material and component I used for the project were difficult to find like pump and buffer for programming.

1.5 LIMITATIONS OF THE PROJECT

It is significant to know that this design is limited to 12v, 5amps electric pump and cannot be used to control industrial water pump above 5 amps.
