Hi, my name is Alejandro and I'm spanish, I'm interested in this project because I'm trying to do the same, monitoring temperature, humidity and CO2 concentration in a room with the DHT22 and MH-Z19 sensors connected to a NodeMcu LoLin. I would like to achieve as you have it.
I would like to know if you could help me with any questions I have. For example, I can not see decimals in thingpeak, although on the Arduino IDE serial monitor if they appear to me, do I have to configure something in thingspeak?
Thank you very much,
Alejandro

Hi Alejandro.
Thanks for expressing interest in my project.
As for your question about the precision of data sent to ThingSpeak I can answer that no extra setup is needed. Make sure you convert data properly in your sketch.
And based on your channels feed I see you've alreade sorted this out.
Best regards,
Anton
