The ESP Devices are most popular devices for IoT(Internet of Things). In this video, you will learn how to create a web application with realtime database. I have used the DHT11 Sensor for logging the data. You could replace it with any other sensor as i have explained it in detail in this video.
This video also includes fixing web application errors.
Incase you are new to firebase, then you are recommended to watch this video in which i have covered most of the common mistakes done by users while using Firebase. • How to fix errors with...

Library for DHT11 :

Link to Firebase:

Thank you! Your video really helpful
I love the explanations you give in your videos
Thank you
Which firebase esp32 client library version is used
Hello there! I tried your method and I got a error that said firebase is not defined, may I ask what might be the reasoning for it?
Great tutorial btw, thanks for the great help!
Hello, ilove your videos, can you do one video where you also include the esp 32 on the gas detection system, that the data can be accessed on a web application as well as on the lcd display
Sure ... I ll try to implement that soon
@@ElectronicsSimplified7 that would be great, let me turn on notifications
I am considering working on it next ... 😃

can we add soil moisture sensor on the same nodemcu esp8266 board? but using different pinmode. can u show the tutorial by adding the soil moisture sensor on the same board..tq
i added 3 sensors soil moisture LDR dht11
tried it, but in the database there are only the tablenames with value: 0 created.
The sensor readings are correct in serialmonitor. only the table is not filling with data. what could wrong?
DHT_11
Humidity
:0
Temperature
:0
If the serial monitor shows the readings. It means the system is working fine. But if the database isn't reflecting the change after every interval that is mentioned in the code. It means that the database has not connected properly.
Bro how can i connect u . I have some doubts bro, just im building a energy meter which is to be connected to firebase and i want to retrieve data to an app which is used to billinga and generation of bills .
Mail me
How can we connect ultra sonic sensor to eps8266 ans send its data to firebase database and create a webpage from it
did you get an answer on this question
I need information about this subject
send me
I can mail you the project. Please contact me via electronicsengineering3@gmail.com

hi, i am getting this error "Failed to Read from the Sensor
REASON: Invalid data; couldn't parse JSON object, array, or value." Can you help me with this
Your connection has an issue
Facing the same error, if I try to read the sensor data on serial monitor locally without the firebase connection the sensor seems to be working fine but when I try with firebase code it gives me the same error@@ElectronicsSimplified7
i have the same problem
Check that your sensor is connected correctly and you have firebase configured correctly.
hii i am getting the same error. Did u solve urs?
Firebase.ready and Firebase.RTDB.set or Firebase.RTDB.get these methods are not there. What to do for this?
Did you install the firebase dependencies?
@@ElectronicsSimplified7 Yes
Even if the firebase is ready. I am facing this error
Request failed:
send request failed
It's hard to debug with this information.
Please tell me more about the project
@@ElectronicsSimplified7 Just I am trying to send one string value to the Real time database at that time I am getting this error.
