Things to consider while preparing the project circuit

The working logic and formula of the sensor should be understood. Since the pulse signal is a simple square wave, recording and converting liters/min (using the formula below) can be done easily.
Formula: Pulse frequency (Hz) / 7.5 = flow rate (liter/min)
The image is sharpened by turning the potentiometer on the contrast setting of the 2x16 LCD I2C display with a pointed screwdriver.

CALCULATING WATER CONSUMPTION

Calculating water consumption

By paying attention to the cable colors of the sensor, it is ensured that it is attached to the correct pins.
Cable plugging and unplugging should not be done while the Arduino is connected to power. This may cause a short circuit.
Breadboard is supported for duplication of pins on Arduino.
The contact of the Arduino circuit with water should be prevented. Taping is done for the isolation of the cable connections.
The pin names used in the sensor connections on the Arduino must match the pins in the code file.
For the connection of the water flow sensor and LCD (16x2) with Arduino, the given image should be followed. (Image 2)

Water Control

To find out how your school uses water, how much water is used and how you can reduce it:
- Students can be divided into teams to walk around the school counting and listing everything that uses water.
- Students can research how much water each device uses and brainstorm ideas to reduce it.
Water uses
All results are put together in tables and graphs and/or on a poster.
If possible, the created posters can be displayed on the school boards.
An example of a school related to the studies carried out on water consumption can be viewed from the link below.
The following website can be examined to raise awareness about the conscious consumption of water.
Students can observe how much water they use in daily life. They can research technological systems that reduce water consumption on how to control this.
HOME TASK 1: The students are asked how many liters of drinking and potable water they use daily. The results are noted. Students are asked to measure the amount of water they consume daily using the project they did in the math class.
Estimated and measured water quantities are compared during the lesson.

This lesson is divided in 3 major parts

Before the lesson students are asked to observe the water consumption in the school washrooms.

Part 1

PART 2

Water Consumption Debate

Divide the class into pairs or small groups, give each group a worksheet, ask the following questions: The students will conduct an experiment to test insulation materials.

- What are the approaches you used during your observations and what results did you reach?

- What is the importance of water for living things?

- What are the problems caused by the reduction of water resources?

Water Consumption Discussion Outcome

Their answers are collected and displayed on one page. The subject is checked and discussed.

You can show a movie about water consumption.

Have students design and put together an informational poster with their answers.

Place the above questions and answers around the school.

To raise awareness in the school, relevant movies can be played on monitors around the school during lunch hours during a water awareness week.

PART 2

How much water do you think we waste when we forget to turn on the tap while brushing our teeth?

An example tooth brushing scenario is considered and the formula for the amount of water that unnecessarily flows from the fountain during tooth brushing is as follows.

Q = A x V

Q: Amount of water spent A: The area of the spout V: Speed of flowing water.

A= π.r2

The following method can be used to calculate the amount of water consumed in a practical way:

Step 1: Put a large bowl under the tap.

Step 2: The stopwatch is prepared and the tap is opened for 10 seconds.

Step 3: The amount of water flowing in 10 seconds is measured and calculated in minutes.

Step 4: An average tooth brushing time is determined. (x minutes)

Step 5: The amount of water flowing for x minutes is subtracted from the amount of water turned off while brushing teeth and the amount of

water saved is found.

Can water flowing from taps be controlled?

With this question, students are provided to realize the problem

Arduino is briefly mentioned to raise awareness of students.

Arduino is an open-source microcontroller platform developed for easy use by anyone who is interested in electronics.

Arduino can read signals from various sensors, flashlights, start motors; In short, it can make all electronic applications you can think of.

Can the flow of water flowing from the tap be measured and controlled using a sensor using Arduino? With questions such as, students are provided to think about the subject.

Then, the materials to be used for the project that will solve the problem

of excessive water consumption are introduced by using the arduino and sensors that were designed before.

• Students are divided into their groups in the 1st lesson. (4 people depending on the class)

• The necessary materials for their designs are provided to the groups by the teacher.

Creation of the Project

Visual 1

• A jumper cable is attached from the gnd pin of the Arduino to the (-) negative pole of the breadboard.
• A jumper cable is attached from the 5v pin of the Arduino tothe (+) plus pole of the breadboard.
• Thus, the limited 5v and gnd pins on the Arduino are replicated with the help of the breadboard.
• Connection of Yfs 201 water flow sensor cables:
• Red wire: to the (+) terminal of the breadboard
• Black cable: To the (-) pole of the breadboard
• Yellow cable: The sensor connection is completed by attaching it to pin 2 of the Arduino's digital pwm pins.
• 2x16 LCD I2C display connection:
• VCC: To the (+) pole of the breadboard
• GND: To the (-) pole of the breadboard
• screen connection is completed.
• One end of the Yfs 201 water flow sensor is connected to the end of the tap with a hose and tightened with a cable tie to prevent water leakage. If necessary, it is supported with hot silicone.
• A hose is attached to the other end of the Yfs 201 water flow sensor and the water is allowed to flow from there.

Explaining the Project

For example, what the project aims at, what it will test and how it will be executed.

The project will provide savings by reducing the water used by consumers.

Thanks to the project created, water will be saved by ensuring that the water flowing from the taps flows in a controlled manner.

In the project, the water flow sensor is connected to a pipe. If the outlet valve of the pipe is closed, the output of the water flow sensor is zero (No Pulse). There will be no interrupt signals seen on pin 2 of the Arduino and the flow frequency count will be zero. In this case, the code written inside the else loop will work.

If the pipe's outlet valve opens, water flows through the sensor and turns the impeller inside the sensor. In this case, we can observe the pulses generated from the sensor. These pulses will act as an interrupt signal to the Arduino UNO. For each interrupt signal (rising edge), the number of the flow frequency variable will be increased by one. The variable Current time and Cycle Duration provides the flow frequency value per second to calculate the flow rate and volume. After the

calculation is finished, the flow frequency variable is set to zero and the whole procedure is started over.
