With the ESP8266 we will be able to read the temperature and humidity from the DHT11 sensor and upload it to Firebase realtime database then the data can be viewed from the web page from anywhere.
First, you will need to connect the sensor to the esp
^ Something like this (i did D2 though instead of D3)
then edit the WiFi and Firebase information in the Arduino sketch Sketch
and add the Firebase config in index.html
You should be good to go now :)
Well this is not a completed project.
i would mainly say it's missing authentication so that only the owner can edit and view the DB.
