This document describes a project to create an automatic water level detector and motor controller using an Android app. The project aims to address the problem of unnecessary water wastage from overflowing overhead tanks in houses in Bangladesh. The system would use a water level sensor to detect the water level and send signals to a microcontroller. The microcontroller would then control a motor pump to switch on or off as needed to regulate the water level. The system is intended to help preserve drinking water supplies in Bangladesh.

2. ABSTRACT:
The drinking water crisis in Bangladesh is reaching alarming proportions. It might very soon
attain the nature of global crisis. Hence, it is of utmost importance to preserve water. In many
houses there is unnecessary wastage of water due to overflow in Overhead Tanks. Automatic
Water Level Controller can provide a solution to this problem. The operation of water level
controller works upon the fact that water conducts electricity. So water can be used to open or
close a circuit. As the water level rises or falls, different circuits in the controller send different
signals. These signals are used to switch ON or switch OFF the motor pump as per our
requirements.

4. INTRIDUCTION:
An Water Level Indicator may be defined as a system by which we can get the information of
any water reservoir. Water level indicator system are quite useful to reduce the wastage of water
from any reservoir, while filling such reservoir. A simple water level indicator can be made
using the EAB. For this you may design a water sensor by using any The wire with Black colour
is connected to Vcc of the EAB. The wires with colours Blue, Red, Green & Yellow are adjusted
to check Level1, Level2, Level3 and Level4 respectively. Each of these four wires are connected
to the amplifier. This amplifier will amplify the signal and will provide the respective logic to the
microcontroller. Then the program logic inside the microcontroller will give the respective
output.
Components
The Components required for building the water level indicator application are:
Embedded Application Board
LED board
Water Sensor (Conducting Wires)
Jumpers
Water Beaker
Transistor (BC548)
Resistor(1K and 470 Ohm)
Breadboard or Vero board. (1 nos)
Power Supply (9V DC)
