WATER LEVEL DETECTION AND AUTOMATIC PUMP

CONTROL BY CHINMOY KUMAR GSHOH B P PODDAR INSTITUTE OF MANAGEMENT AND TECHNOLOGY

INTRODUCTIONAutomatic water pump controller is a series of

functions to control the Automatic Water Pump Controller Circuit in a reservoir or water storage.

The water level sensor is made with a metal plate mounted on the reservoir or water tank.

With a sensor in the short to create the top level and a detection sensor for detecting long again made for the lower level.

And ground lines connected to the bottom of reservoirs.

RELATED WORKSKhaled Reza el al., (2010) introduced the notion

of water level monitoring and management within the context of electrical conductivity of the water.

The authors motivated by the technological affordances of mobile devices and the believe that water level management approach would help in reducing the home power consumption and as well as water overflow.

The research result was a flexible, economical and easy configurable system designed on a low cost PIC16F84A microcontroller to determine and senses water level globally.

MATERIALS There are some objectives need to be achieved in order to

accomplish this project. ARDUINO ULTARSONIC SENSOR WATER PUMP PCB BOARD SOLDERING RELAY TRANSISTOR 2N2222 RESISTOR CAPACITOR SWITCH LED WIRE FEMALE-HEADER MALE-HEADER BUZZER 16 X 2 LCD

HARDWARE DESIGN

The system performs the sensing level and control activities without the manual observation and attention in the site. Being an automatic system unavailing manpower and providing information for long period of time. The automatic water level control system has the following main components

SENSOR UNIT

The sensor assembly consists of four aluminum wires arranged at 1/4, 1/2, 3/4 and full levels in the tank. The dry ends of these wires are connected to analog input pins A1, A2, A3 and A4 of the Arduino respectively. A fifth wire is positioned at the bottom of the tank.

CONTROL UNIT

The basic operation of control unit is the controlling water pump by arduino which is programmed by particular program. Water pump are connected with an output pin of arduino via a relay circuit which is connected with a transistor.

BUZZER

It is an electronic used to give alarm sound as it is programmed

LIQUID CRYSTAL DISPLAY (LCD) LCD (Liquid Crystal Display) screen is an

electronic display module and find a wide range of applications. A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits.

A 16X2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data.

The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task.

SIMULATION Using PROTEUS software, now it is possible to

draw a complete circuit for a arduino based system and then tests it.

With PCB layout the software now also offering automatic of both component placement and track routing, getting the design into the computer can often be the most time consuming element of the exercise.

So when we simulate our program which had written in arduino C language, and as we wrote before that will show the water level on the LCD and will turn - on and off- the pump unit according to this value
