Project Description:
********************
In my last tutorial on the Google Firebase Database, I explained how to send a sensor value from the Nodemcu ESP8266 Wifi Module to the Google Firebase Database. In today’s episode we are going to make the same exact thing using the ESP32 Wifi + Bluetooth Module by the Espressif Systems. This is the same exact company that created the ESP8266 series of chips, modules, and development boards.

As this is a getting started tutorial, I will try to keep things simple so that you can easily follow this tutorial. I will be using a variable resistor or potentiometer as the Sensor.

In this tutorial, we will cover,

1. Circuit Diagram Explanation
2. How to set up your Google Firebase Database Account
3. ESP32 Firebase programming and finally
4. Testing

sir I searched for 2 hrs. and got only one perfect video thanks a lot sir

[FLTOMM]

Perfect video !!! Greet!! Congratulations! Tks!

[pbltimbangan]

thankyou for this tutorial
halo sir. in this video, you save the data in firebase with this node
>>> Sensor > data = //value
how to save the data with more node, example
>>>Sensor >> Input > data=//value
.
thankyou,

Followed everything but it says error compiling for board esp32 dev module

[TzikasVasilis]

Did they change something? This project used to work some months ago... FAILED
REASON: connection refused :(

hello sir, do you have any idea how to send data to firebase usinh esp32, but the data is inside a quotation?
ex. "178"
instead of..
ex.178

[yoshuadennish]

if i want to build similar project but with relay. can i add node-red mqtt software between firebase and IoT device instead of direct communication IoT and firebase? and what do you think is it necessary to add low bandwith communication between IoT and node-red?

[KarthikR-lupr]

Hello bro, we're doing an IOT project named Gas Leakage Monitoring System using Arduino. We know how to do hardware part but the problem here is we have to create either a web application or mobile application on our own and we need to link it with our IOT project. We don't know how to do it because we're new to this branch. I hope you will help me to solve this problem. Hoping for your good reply!
