1.PROJECT BACKGROUND
The Water Level Controller project was designed to help in controlling the water level in the
tank or container. This project has a system to monitor or sense the water level in the tank so it
will automatically give a signal to us whether the water in the tank is already full or not so we
can stay alert and stop the water once it has filled up the tank. A water sensor is used to indicate
the level of water in the tank so it can prevent the water from overflowing. Light Emitting
Diodes (LED) and buzzer are used to show the signal that the water has reached the fixed level
and we must stop the water before it overflows. As a conclusion, the project is very useful and
beneficial to our society because the water level controller can help us to stay alert when we
need to fill up the water tank so it can prevent us from wasting the water and save our pocket
money because we can stop the water on the time when the system gave us the signal.

2.INTRODUCTION
A water sensor is a device used in the detection of the water level for various applications.Water
sensors are installed in data centers to reduce all potential hazards and consequences of water
leakage.Industrial applications of water level sensors include water level sensing in transport
and storage tanks and water treatment tanks.
Figure 2.1
Based on the Figure 2.1, this is the type of water sensor that has been used for the
project. The sensor is mainly comprised of three parts:
1) An electronic connector
2) A 1 M resistor
3) Several lines of bare conducting wires
This water sensor is intended for water detection and can be used to detect rainfall, overflow,
and even liquid leakages.The sense tracers are interleaved between a set of exposed traces
connected to ground to make this sensor work. The 1 M pull-up resistor is used on the sensor
tracers. The sensor trace value will be pulled high by the resistor until a drop of water shorts
the sensor to the grounded wire. This module can be used with the analogue pins to detect the
amount of water between the grounded and sensor tracers.This item determines the water level
by measuring the amount of water present using a number of exposed parallel wires. The
advantages of this sensor is that it consumes only a little power and it is extremely sensitive.

3. OBJECTIVE
There are several objectives that need to be achieved in this Automatic Water Level Controller
project which are:
1) To build an automatic water level controller that can prevent water wastage that often
occurs in industry and homes by giving a warning when water reaches its maximum
level.
2) To design a water level controller that can facilitate the measurement process of water
in a large tank without having to look directly into the tank.
3) To build a automatic water level controller that can detect leaks that occur in the tank
when the water level does not exceed the desired level

4.METHODOLOGY OF PROJECT
Based on our project which is Automatic Water Level Controller.In this project, we have
built something that is very useful and convenient for us nowadays. In producing this project,
we have used PIC18F4580 as a microcontroller. Indirectly, our project has a water sensor where
this sensor serves as a detector of the presence and height of water in the water tank to send a
signal to the PIC to be processed to produce output. In this case, the sensor has been connected
to the PIC and the sensor is also placed into a prototype tank that we have built and then the
tank will be filled with water. After that, the sensor will detect the water level and the presence
of the water and send it to the PIC. The PIC will process the data generated from the sensor
that is temporarily stored in the port. Once it is finished in the process, it will produce an output
that is an LED will light up and a buzzer will ring when the water reaches the maximum point
in the tank which indicates that the sensor has detected the water. Therefore, with the LED and
buzzer that have been activated, it will give a warning or instruction to the user to close the
flow of water from entering the tank to prevent the water from overflowing out of the tank.

Based on Figure 6.1, there is a flowchart program built based on the program we designed to
produce this Automatic Water Level Controller project. This flowchart also summarized and
explained the journey of the existing system behind the coding that we have built to produce
this project.

7. SCHEMATIC DIAGRAM
Figure 6.1
Based on figure 6.1, by using a push button to symbolize the water sensor. After sensing water
at the maximum level, the water sensor will give a digital result. Then, the PIC microcontroller
will receive the digital output as an input. As a result , the buzzer will make a noise as a warning
and the LED will light up, the output is presented.This indicates that the water has been at its
highest level and needs to be stopped to prevent water overflow and waste. The buzzer and
LED will turn off as soon as the water in the tank is reduced or does not trigger the sensor.

Result
Figure 9.1
Based on Figure 9.1,This image shows a prototype of the Automatic Water Level
Controller. As can be seen, there is a prototype tank attached together with a sensor to
detect the height of the water level in the tank. Then, there is a PIC18F4580 that
serves as a microcontroller for our project and further there is a connection that we
have done on the PIC port along with hardware consisting of buzzers and LED to
produce output for this project.

Troubleshooting
Based on this project, there are some problems that arise in producing this project such as :
-
Coding revenue
The problem that arises in generating coding is when there is an identified error coming from
the placement of data on different ports. So we solved it by converting to the actual port
-
Wrong wire connection
In this problem, we found that the LEDs and buzzers were not working properly. So, we find
and identify the main cause of it happening. Once identified, we immediately fixed the wire
connection and the LED and buzzer could work according to the program.

10.DISCUSSION
Based on the result obtained from this mini project, the Water Level Controller project had
achieved the objectives which are it can prevent the wastage of water that occurs either in
industry or home. Other than that, this project can also measure the water level in a large water
tank because it uses a water sensor to detect the presence of water. This project is very
beneficial to use at industry or home because it is easy to set up at the water tank and easy to
use without any complicated setting of the system. Even though the system still needs to
improve due to its disadvantages such as the system of the project must be operated manually.
For example, when the sensor detects the presence of water the user must stop the flow of water
and close the system to stop it. Furthermore, the project can also just detect only a level of
water that is present in the water tank. However, this project can operate successfully and can
be used in real life and with some developments it will be a very excellent project in the future.
11.CONCLUSION
As a conclusion, the Water Level Controller project was designed to help in controlling the
water level in the tank or container. The project uses a water sensor as a main component for
the system to operate with the help of Light Emitting Diodes and buzzer to give a signal for the
user to close the water flow once it had reached the fixed level. This project is very beneficial
to be used at home or industry due to its system that is easy to set up and use. This project can
help its users to overcome the wastage of water problem and save our pocket money at the
same time. Last but not least, this project will have a high impact and become very crucial in
industry due to its functionality that can help us control the water level.
