WATER LEVEL INDICATORMODULE - 5

AAVISHKAR LAB | 2017 3

No one can survive without water. All living beings, i.e. human beings, animals and plants need water to survive. It is the source of all life on earth.

WATER CONSERVATION AND EDUCATION

INTRODUCTION

Water is the most precious gift of nature. It does not taste, does not smell and does not color. It is found everywhere and its other name is Life. We find it in such a form as ponds, wells, rivers, floods, waterfalls. Almost three-fourths of the Earth's surface is covered by water. You should save water and save for water conservation. If you save water, then it will be sufficient water supply for your fu-ture generation. Although large amounts of water can be recycled, but large power, energy and money are spent in it. A pond, oceans, clean water in rivers ensures the healthy life of animals. Millions of people around the world are still deprived of clean and safe drink-ing water. That is why we will contribute to the water conservation through this project. Water is precious gems of nature and we have to try to save the water.

Why this project?

Through this project you can see the eligibility of the water tank.

So that we can close the motor timely and avoid wastage of

water.

How the Environment will be protected?

Water is Life! That's what we say, but no one cares for it to avoid wastage of water. In the morning, when the water comes in the tap, you start the motor to fill the tank on the house, and if there is no attention, the motor continues to flow even when the tank is full and the water is flowing unnecessarily. This causes elec-tricity and water misuse. When we close the motor, it is wasting 100 to 200 liters of water. We know only 3 percent is sweet wa-ter. And the remaining 97 percent is salty water. But if you do that, then you have to buy the water for a drink like petrol a few years later.

Water is misused in many ways. To avoid wastage of water, you can build this project.

AAVISHKAR LAB | 2017 6

1. Is there any leakage in the tap water of your house? If yes, then almost 5000litre water gets wasted.

2. From this, you can decide how much water you are saving in a year.

3. Also saving the electricity.

How much will be saved ?

AAVISHKAR LAB | 2017 7

1. Make sure all the components are available in the box given to you,

• Printed Circuit Board (PCB),

• Electronics Components,

• Small Information Book

2. We can build this project by using three components we have given.

3. Information about the electronic components is given in the information book. Read it carefully.

4. As shown in the picture, add electronic components on Printed Circuit Board. Take help from your teachers.

5. Make sure that the electronic components are all at the right places.

6. With the help of your teachers use solder gun and join the electronic components on the PCB. Refer picture 1 for this.

7. When all the electronic components are joined to PCB then the project is ready to use.

8. We can use this project, according to the following instructions…...

9. As shown in picture 1, there are connector, two lights, DC Jack, light and red colour light.

10. Mounted power supply to DC Jack.

11. As shown in picture 2, arrange the wires from COM to L4 in the water tank. If the red LED is glowing then the project is working. Put the water in the tank, you will see that as the water tank is filling up then the blue LED is glowing.

12. Just like this we can save the water.

STEP 1

AAVISHKAR LAB | 2017 10

Picture shows Solder Gun, Cutter and Solder Wire. With the help of them we have to mount (solder to connect) electronic component on PCB.

P.C.B. and Resistor of 1k ohm are shown in this picture.

STEP 2

STEP 3

AAVISHKAR LAB | 2017 11

STEP 4

As indicated in this picture, the resistors of 1k ohm are mounted on the holes of P.C.B. as shown in the above figure. Mount them with the help of Solder gun.

STEP 6

This picture shows the back side of the P.C.B.

The Picture shows the components are mounted on the track on the back side of the P.C.B. with the help of Solder Gun.

AAVISHKAR LAB | 2017 13

Picture shows how the P.C.B. looks like when all the extra part of components are removed.

Picture shows the backside of P.C.B. where components are inserted into holes from the front side of P.C.B.

In this picture the components are mounted (connected) on the track of backside of the P. C. B. with the help of Solder Gun

Picture shows that the extra part of component is removed with the help of Cutter.

STEP 7

This picture shows that the resistor of 330 ohms is mounted in the holes of P.C.B. as shown in the below figure. And mount them with the help of Solder Gun.

AAVISHKAR LAB | 2017 15

STEP 8

This picture shows the transistor and it has three terminal Base, Collector, Emitter. And to mount the transistor on P.C.B., tilt the ‘base’ terminal back side.

STEP 9

As shown in this picture, mount transistor into the holes of P.C.B.

AAVISHKAR LAB | 2017 16

The Picture shows the L.E.D. with two terminals positive and negative. The Positive terminal is called as Anode and negative terminal is called as Cathode.

The positive terminal wire of L.E.D. is longer than the negative terminal wire.

STEP 20

As we can see in the picture, all the four L.E.D.s are glowing because, all the four sensor L1, L2, L3, L4 are in the water. It indicates that the water tank is full.

STEP 21

As we can see in this picture, three L.E.D.s are ON because sensors L1,L2 and L3 are in water and sensor L4 is out of the water that’s why one L.E.D. is OFF.

STEP 22

As shown in this picture, two of the four L.E.D.s are ON and other two are OFF, it happens because two of the four sensors L1 and L2 are in the water and the sensors L3 and L4 are out of the water. It means the level of water is decreased.

STEP 23

As we can see in this picture, only one sensor L1 is in the water and sensors L2, L3 and L4 are out of water that is why only one L.E.D. is ON. It means that the level of water decreased or very low.

STEP 24

Picture shows that, all the L.E.D.s are OFF because all the sensors, i.e., L1, L2, L3, L4 are out of water. Which means the water tank is empty.
