![]() You need to insert your network credentials, project API key, database URL, and the authorized user email and password. Datalogging-Firebase Realtime Database CodeĬopy the following code to your Arduino IDE or to the main.cpp file if you’re using VS Code. Now, you’re all set to start programming the ESP8266 board to interact with the database. For that, wire the sensor to the default ESP8266 SCL ( GPIO 5 (D1)) and SDA ( GPIO 4 (D2)) pins, as shown in the following schematic diagram. We’re going to use I2C communication with the BME280 sensor module. So, you need to wire the BME280 sensor to your board. In this tutorial, we’ll send BME280 sensor readings to the Firebase Realtime Database. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! * you can also test the project with random values instead of sensor readings, or you can use any other sensor you’re familiar with. BME280 or any other sensor you’re familiar with.ESP8266 board (read best ESP8266 boards comparison).Send sensor readings and timestamp to the realtime database as an authorized user.įor this project, you need the following parts*:.Get epoch time (timestamp) from an NTP server.Get BME280 readings: temperature, humidity, and pressure.Authenticate as a user with email and password ( the user you set up in this section).In this section, we’ll program the ESP8266 board to do the following tasks: 6) ESP8266 Datalogging (Firebase Realtime Database) You’ll better understand how this works when you start working with the ESP8266. ![]() With our security rules, it can read and write data to the database under the node UsersData/ RjO3taAzMMXBB2Xmir2LQ. If there are other data published on the database, not under a node with the users’ UID, that user can’t access that data.įor example, imagine our user UID is RjO3taAzMMXBB2Xmir2LQ. This means the user can only access the nodes that are under a node with its corresponding user UID. This grants that each authenticated user can only access its own data. These rules grant access to a node matching the authenticated user’s UID. Getting Started with VS Code and PlatformIO IDE for ESP32 and ESP8266ġ) Go to Firebase and sign in using a Google Account.Ģ) Click Get Started and then Add project to create a new project.ģ) Give a name to your project, for example, ESP Firebase Demo.If you want to program the ESP boards using VS Code with the PlatformIO extension, follow the following tutorial instead: Installing the ESP8266 Board in Arduino IDE (Windows, Mac OS X, Linux).So, make sure you have the ESP8266 add-on installed in your Arduino IDE: Preparing Arduino IDEįor this tutorial, we’ll program the ESP8266 board using the Arduino core. If you use the Firebase project of that previous tutorial, you can skip to section 4) Set up Realtime Database because the authentication methods are already set up. You can continue with the Firebase project from this previous tutorial or create a new project. ESP8266 Datalogging (Firebase Realtime Database).These are the main steps to complete this project: You’ll have a record of all readings on the Firebase realtime database. New readings are added to the database periodically. ![]() ![]()
