This guide will go you started apace with Firebase using the ESP32 board. Firebase is Google'southward mobile application development platform that includes many services to manage data from IOS, Android, or web applications. You'll create a Firebase projection with a realtime database (RTDB), and you'll learn how to store and read values from the database with your ESP32.

In a later tutorial, you'll acquire how to create a Firebase web app that you can access from anywhere to monitor and control your ESP32 using firebase'due south realtime database:

• ESP32 with Firebase – Creating a Web App

We have a similar tutorial for the ESP8266 board: Getting Started with Firebase (Realtime Database)

What is Firebase?

Firebase is Google's mobile application development platform that helps y'all build, improve, and abound your app. It has many services used to manage information from any android, IOS, or spider web awarding.

The following paragraph conspicuously explains the advantages of using Firebase:

"Firebase is a toolset to "build, improve, and grow your app", and the tools it gives you cover a large portion of the services that developers would normally accept to build themselves but don't really want to build because they'd rather exist focusing on the app feel itself. This includes things like analytics, authentication, databases, configuration, file storage, push messaging, and the list goes on. The services are hosted in the deject and scale with piffling to no effort on the part of the developer."

This paragraph was taken from this commodity, and we recommend that you read that commodity if you lot want to understand ameliorate what firebase is and what it allows you to exercise.

You tin utilize the ESP32 to connect and interact with your Firebase project, and you can create applications to control the ESP32 via Firebase from anywhere in the earth.

In this tutorial, we'll create a Firebase project with a realtime database, and we'll use the ESP32 to store and read data from the database. The ESP32 can interact with the database from anywhere in the globe as long as it is continued to the internet.

This means that you tin take two ESP32 boards in dissimilar networks, with one lath storing data and the other board reading the most recent information, for example.

In a later tutorial, we'll create a spider web app using Firebase that will control the ESP32 to brandish sensor readings or control outputs from anywhere in the world.

Project Overview

In this tutorial, y'all'll learn how to create a Firebase project with a realtime database and store and read data from the database using the ESP32.

To follow this projection, starting time, you need to prepare up a Firebase project and create a realtime database for that project. Then, you'll plan the ESP32 to shop and read data from the database. This tutorial is divided into three sections.

1. Create a Firebase Project
2. ESP32: Shop data to the Firebase Realtime Database
3. ESP32: Read information from the Firebase Realtime Database

Let'southward get started!

Ready Up a Firebase Business relationship and Create a New Project

1.Create a New Project

Follow the next instructions to create a new project on Firebase.

1. Go to Firebase and sign in using a Google Business relationship.
2. Click Get Started, and then Add project to create a new projection.
3. Give a proper name to your project, for example: ESP32 Firebase Demo.
   
4. Disable the option Enable Google Analytics for this project as information technology is not needed and click Create projection.
   
5. Information technology will accept a few seconds setting up your projection. And then, click Keep when it's fix.
   
   
6. You'll be redirected to your Project console page.
   

2. Fix Authentication Methods

You need to set hallmark methods for your app.

"Most apps demand to know the identity of a user. In other words, it takes care of logging in and identify the users (in this case, the ESP32). Knowing a user'southward identity allows an app to securely save user data in the cloud and provide the same personalized feel across all of the user's devices." To learn more about the authentication methods, you can read the documentation.

1. On the left sidebar, click on Authentication and so on Get started.
   
2. There are several authentication methods like email and password, Google Account, Facebook account, and others.
3. For testing purposes, we can select the Anonymous user (require authentication without requiring users to sign in first by creating temporary anonymous accounts). Enable that selection and click Relieve.

3. Creating a Realtime Database

The next step is creating a Realtime Database for your project. Follow the side by side steps to create the database.

1. On the left sidebar click on Realtime Database then, click on Create Database.
   
2. Select your database location. It should be the closest to your location.
   
3. Set security rules for your database. For testing purposes, select Start in test mode. In after tutorials you lot'll larn how to secure your database using database rules.
   
4. Your database is now created. Yous need to re-create and save the database URL—highlighted in the following image—because you lot'll need information technology after in your ESP32 code.
   

The Realtime Database is all set up. Now, you also demand to become your projection API key.

4. Go Project API Fundamental

1. To get your project's API key, on the left sidebar click on Project Settings.
   
2. Re-create the API Key to a safe place considering you'll demand information technology later.
   

At present, yous have everything ready to interface the ESP32 with the database.

Program the ESP32 to Interface with Firebase

Now that the Firebase Realtime Database is created, you'll learn how to interface the ESP32 with the database.

To program the ESP32, y'all can utilise Arduino IDE, VS Code with the PlatformIO extension, or other suitable software.

Note: for firebase projects, we recommend using VS Code with the PlatformIO extension considering if yous want to develop a web application to make the span between the ESP32 and Firebase, VS Lawmaking provides all the tools to do that. However, we won't build the web application in this tutorial, so you lot can use Arduino IDE.

Install the Firebase-ESP-Client Library

At that place is a library with lots of examples to utilise Firebase with the ESP32: the Firebase-ESP-Customer library. This library is uniform with both the ESP32 and ESP8266 boards.

In this tutorial, nosotros'll expect at simple examples to shop and read data from the database. The library provides many other examples that you can check hither. It as well provides detailed documentation explaining how to apply the library.

Installation – VS Code + PlatformIO

If you're using VS Code with the PlatformIO extension, click on the PIO Home icon and and so select the Libraries tab. Search for "Firebase ESP Customer". Select the Firebase Arduino Client Library for ESP8266 and ESP32.

Then, click Add together to Project and select the projection you're working on.

Also, change the monitor speed to 115200 by adding the following line to the platformio.ini file of your projection:

          monitor_speed = 115200        

Installation – Arduino IDE

If you're using Arduino IDE, follow the adjacent steps to install the library.

1. Become to Sketch > Include Library > Manage Libraries
2. Search for Firebase ESP Client and install the Firebase Arduino Customer Library for ESP8266 and ESP32 by Mobitz.

Note: We are using version two.three.7. If you have issues compiling your code with more recent versions of the library, downgrade to version two.3.7.

Now, you're all set to outset programming the ESP32 board to interact with the database.

ESP32 Store Data to Firebase Database

Re-create the following code to your Arduino IDE. This sketch inserts an int and a float number into the database every 15 seconds. This is a simple example showing y'all how to connect the ESP32 to the database and shop data. This is also compatible with ESP8266 boards.

Note: We are using version ii.iii.seven of the Firebase ESP Client library. If y'all have issues compiling your code with more than contempo versions of the library, downgrade to version 2.3.7.
