Firebase Connected NodeMCU Park Project

This project integrates Firebase Realtime Database with a NodeMCU-based IoT system to monitor and notify the status of a parking lot. It also uses the Vonage API to send SMS notifications about the parking status.

Features

• Real-time monitoring of parking lot status using Firebase Realtime Database.
• SMS notifications sent to a predefined phone number using the Vonage API.
• Node.js-based backend for handling Firebase and Vonage integrations.

Prerequisites

Before setting up the project, ensure you have the following:

• Node.js installed on your system.
• A Firebase project with a Realtime Database configured.
• A Vonage account with API credentials.
• A valid serviceAccountKey.json file for Firebase authentication.

Installation

1. Clone the repository:

   git clone <repository-url>
   cd iot_firebase_park_project

2. Install dependencies:

   npm install

3. Add your Firebase service account key:

   • Place your serviceAccountKey.json file in the root directory of the project.

4. Configure Vonage API credentials:

   • Update the apiKey and apiSecret in index.js with your Vonage credentials.
   • Replace the phoneNumber variable with the recipient's phone number.

Usage

1. Start the application:

   node index.js

2. The application will listen for changes in the Firebase Realtime Database and send SMS notifications when the parking lot status changes.
