Arduino SIM800L DHT11 Firebase | Send Sensor Data to Firebase using Arduino UNO

In this video, I will show you how to send temperature and humidity data to Firebase using Arduino UNO and SIM800L. There are many cloud platforms like ThingSpeak, Adafruit.io, Blynk, and IFTTT, etc. But I will use Firebase, because I did not find any content on this platform about sending sensor data to Firebase using Arduino UNO and SIM800L.
I did not use any library for SIM800L GSM module. I have write my own code using AT Commands to send data to Firebase. You can download the code by using link below.
