Smart Parking System

🔍 About the project

Intelligent parking system connected to firebase and managed by a realtime web application. The system has access card reading, parking availability, alarm system and real time monitoring.

🔮 Technologies Used

💻 Website

Once authenticated in the system, this will be the page with information about the parking lot. All data is updated in real time.

🔥 Firebase setup

All you need to do to configure the backend with your Firebase project is to go into the /ParkingApp/.env directory and change the FIREBASE_API_KEY and DATABASE_URL variables

FIREBASE_API_KEY= ...

DATABASE_URL= ...

JWT_SECRET= ...

Then go to the /ParkingApp/src/frontend/src/script/firebase.js directory and insert your database URL

const firebaseConfig = {
    databaseURL: ""
};

Finally, go to the /ParkingApp/src/frontend/src/services/realtimeService.js directory and insert your database URL

const DATABASE_URL = "";

💡 How the Circuit Works?

• Reads the card and checks if it has a valid ID in the system. If authorized, a green LED will light up and a gate represented by a servo motor will open. If the card is declined 3 times, an alarm will sound and a red LED will flash.
• An LCD display will inform the driver whether there are available spaces or not. If there are none, the parking lot will be inaccessible.
• The parking space will be monitored by an infrared sensor
• All parking operations will be monitored through an Android application, which will inform: available parking spaces, ID of the last card used, ID of the last card declined, number of times the alarm was activated and system connection status.
