ESP8266 DHT11 SIM800L | GSM Based Temperature Monitoring with NodeMCU

Sir, When we using MQ sensor for this (without DHT11), how can I modify it?

Thank you very much for your wonderful tutorial. I have a question. How is the ESP8266 powered? From what I see in the video and in the diagram, the battery is only connected to the SIM800L.

I wonder how to do a connection or a wiring diagram of esp8266 as the main board and is connected with gsm sim900a and a flame sensor. Where in the values of the flame sensor in the database will be shown or projected to our website.

is the code the same if using esp32?

Sir kindly make a video of how we can send data to the cloud server by only using GSM Sim900a or any other gsm module
I've tried but it's not working I can make calls from mobile to gsm but from gsm to mobile calls are not happening.
I think there is an issue with the API key kindly help me.

SIM800 connects to the network (blinks after three seconds) but doesnt do any serial communication with esp8266. Nothing gets printed on serial monitor and sim800.available is always zero. Any ideas how to fix this?

Please make a tutorial how can I send this data to firebase (requested previously also). ...The great thing about your tutorials is that you put the download link of the concerned libraries within the code. Try to add Urdu audio for better explanation. Thanks for your worthy tutorials.
