Diy Big Ultrasonic Sensor That Works Like Real

Hey there if you are reading this intructable then definitely you might have got the attention of the size of this ultrasonic sensor, It is not just a plane model but this works like the regular ultrasonic sensor.

If you are new and don't know what an ultrasonic sensor is let me explain it to you in a simple way, It is a small electronic component that is used in most of the Robotics project which requires obstacle sensing.

In the ultrasonic sensor from the one end ultrasonic waves are emitted and from the other and the ultrasonic signals are received and during the transmission if any obstacle is detected this hardware finds that and can tell the controller to control various other components attached to it.

This big ultrasonic sensor can be attached to your very big robotic projects since the working remains the same but only the size is different.

Now if you are thinking why I made this project I don't have a direct answer for this but if you are good at something applying creativity in a unique way is a very good thing! and also this is the most uncommon HC-SR04 you and i might have seen so far and a good desk toy.

To begin with, I have given all the steps that I followed to build this project, Also you can see the working of this sensor given at the end of this instructable.

Supplies

Ultrasonic sensor

Ruler

Cardboard

Paint and brush

Pen and paper to take down measurements

Plastic bottle

Popsicle sticks

Aluminum foil

Steel mesh

Hot glue and paper glue

Soldering iron and lead

Arduino board, jumper wires, and breadboard with servo for testing this project

Step 1: Taking Measurements

This is the most interesting part in the project this is because after you take the measurement it is totally left to you as to which scale you will be building this project.

It can be scaled to 5x, 10x or even 20x the only limitation is the resources you have, I made a marking and made a note of all the measurements first and then later traced them on a piece of cardboard.

There are lots of other building materials but I think working on the cardboard is very easy and it can be found commonly everywhere.

I recommend to use single and hard pieces of cardboard and avoid using multi-layer of cardboard that is found in the carton box this is because this will spoil the look of the overall project.

Step 2: Breaking Down the Sensor

After you made a note of all the measurements of the sensor we need to desolder the components.

First, let's start with the transmitter and receiver Parts, I recommend you to make a small marking on these parts before your desolder because both the components look exactly the same.

After the part is desoldered from the main board I used a wire of 15 CM length to solder between the board and this sensor component.

Here you can also use jumper wires but I choose to use single standard wire because of its strength, Avoid using thick copper wires because it will offer resistance and will cause a decline in performance.

You can see that i have applied same steps on the other part too.

You also can simplify this circuit with a Simple small PCB, Complete your electronic projects in the best way from PCBWay

Step 3: Preparing the Sensor

To make the transmitter and receiver Part like in the actual sensor I made a note of the sizes and traced it on a piece of paper.

later i cut the paper and used it as a template by placing it on the steel mesh and did the same again for other part too.

Now mark the center point in the Steel mesh and place the real sensor modules on this and cut it out a hole and place the sensor inside these holes

Now you can glue this Steel mesh on top of the plastic tubes using hot glue, Later finish this transmitter and receiver part by covering it with a piece of aluminum foil to give it more realistic look.

You can do this by pasting the aluminum foil on a sheet of paper and later roll that sheet of paper into this plastic tube

Step 4: Finishing

To give this big ultrasonic sensor a realistic look I will hand-paint the cardboard with a deep blue color.

The ultrasonic sensor also comes in dark green colour but I chose dark blue, Apply even layers of paint over the cardboard

If you are using a brown sheet of cardboard I would ask you to first paint it with white and later after the paint is dry you can color it with blue

For the crystal oscillator part that is present on the board of the ultrasonic sensor I will fold the cardboard into a small piece of box and later glue it with aluminum foil.

Trim the excess foil and after these parts are dry glue it to the main board using hot glue, Make sure none of the wires are hanging outside.

To make the pins i used popsicle sticks and covered those with aluminum foil to get that silver finish.

Step 5: Testing

To test this ultrasonic sensor I used Arduino nano, microservo, few jumper wires and small piece of breadboard

You can find the codes online for this simple ultrasonic sensor and server control or simply use the arduino code given by me below

After you upload the code to the board just connect the wire to the ultrasonic sensor and servo as per the circuit diagram and place your hand in front of this ultrasonic sensor and now the servo should make a movement

There are many projects you can try to utilize the working of this ultrasonic sensor additionally you also can check the working of this ultrasonic sensor in the serial monitor of IDE.

Hope you love this idea, i suggest you try building this project as you will gain a lot of information on the working of such components.

If you still have any doubts we can always talk on the comments, For detailed working you can check the video below.

Step 6: Working Video

This video not only shows the working of this project but also a step by step tutorial on the build part.

Like I said above the use of this sensor is not just limited to one specific application but can be used in a variety of places, Only the thing is you have to be creative.

This was all about this project, if you want me to make any such big projects from the smaller components let me know in the comments i will try to make that too, Try this project on your spare time, Thank you and good luck
