How do I connect NodeMCU to Google Firebase?
Connect your NodeMCU ESP8266 with your personal computer via standard USB cable and upload code in it. While uploading the code into NodeMCU, the device continuously blinks. Now open the serial monitor form Tools, you will find data are uploaded to Firebase database.
What are the two parameters required for sending or receiving data to from Firebase cloud using NodeMCU?
Right now two parameters viz. humidity and temperature are sent in same parent path and different child path. These two parameters are very important to communicate with firebase. Setting these parameters will enable the data exchange between and ESP8266 and firebase.
How to fetch data from a Firebase Database on NodeMCU?
For this instructable, we’ll be fetching data from a database in Google Firebase and fetch it using a NodeMCU for further parsing. 2) G-Mail account for creating a Firebase database. 3) Download the Firebase Arduino IDE Library and install it on the Arduino IDE. Simply head over to the Firebase console and click on Add Project.

How can I upload data to Firebase using Arduino?
Basically instead of using an Arduino library for Firebase, you can define JS functions, that can store or retrieve your data from the database, deploy them to Firebase and call them in your Arduino sketch through simple https and http calls.
How to add a database to a firebase project?
Simply head over to the Firebase console and click on Add Project. Once that is done, head over to the Database tab and add a Realtime Database. Copy the Host Name from the top of the database and Database Secret Key from Setting>Project Setting>SERVICE ACCOUNTS>DATABASE Secrets.
