Smart parking system using IoT

Hello Techies, We brought the latest project for you this time. Which we named smart parking system using IoT. this is a great system and project for techies, hobbyists,s and project makers. what do you need to make this system and how you can make it we will share all the details. we have uploaded a lot of projects before from our smart irrigation system using Arduino. so you can see our latest project if you are searching for the project. this project may also help you in your parking. when you will park your vehicle it will notify you of all the space near the car. it inside the car you will receive the notification into your mobile phone which is needed to connect to the internet. this is IoT based smart parking system so you need to connect your system always with the internet and make sure about the internet connectivity. this is a very interesting project.

What is a smart parking system using IoT

In this Smart parking system, we need a mobile phone. on which the data from the sensor will be shown. we will see the space when we parked our car on our mobile phone with notification. so, when we parked our car we will not collide because we know how much distance the object from our car. in this project, we use an app that will be shown all the data of the sensor. through this iot smart parking system, we can save our cars from damagesthere is a lot of projects available in the market which works similarly and they are very costly but with this project, you can make your own project which is smarter than theirs. you can make this same project over the Arduino. which will not need internet connectivity. where you can use Bluetooth with Arduino or wire. we have uploaded all the projects you can check these from the category.

How does the IoT-based smart parking system work?

The project uses the server. there is a device known as the nodemcu and the scientific name is esp8266 helps to make this project. this is a wifi enable microcontroller. this device needs internet. so, first, we need to connect the device to the internet. and then we will connect the sensors with the device. when so the sensor sends the value to the nodemcu and this device sends the same data to the server, now we will use an app name blynk which is connected to the server. both devices need to be connected to the internet. nodemcu and the mobile phone. After uploading the code in esp8266. we open this app and make the button, led, and the gauge to make the IoT smart parking system. in this app we will receive all the data. we can connect the sensor at the back of the car and the sensor will send the distance of the object near to the car on the server and the app we are using will receive all the data and showing us to the mobile phone.

 

How to make a smart parking system using IoT

We will make the system step by step. so you can make the system easily by yourself. you need only follow the given steps and components which we are sharing given below. to make this awesome project you do not need to be an expert. only you need to know some basics of electronics and Programming.

if you are not aware of the electronic basic and Simple programming you can buy our Ebook at a very low price and you will surely learn a lot of things from this ebook. buy now

Components Required for Smart parking:-

  • Nodemcu(esp8266)
  • Jumper wire
  • Breadboard
  • Ultrasonic sensor
  • Mobile phone

 }  

when your device will connect you will see the given text on your serial monitor.

Step 1

Download the Blynk app from the play store.

Step 2

open the Blynk app & click on the new project.

 

Step 3

Select nodeMCU from the library

 

Step 4

Token will be sent to your Gmail id. copy that token from the Gmail id and paste it into the code which is given above.

Step 5

Click on the plus sign from the given screen in-app.

 

Step 6

add 5 led

 

 

Step 7

add 2 gauge

Step 8

Set led with the name of safe 1 to safe 5 and decide color

Step 9

Set gauge from 0 to 100, 255 value.

Now you can see this working in the phone screen.

 

Thanks to all, all the best for the project.
