ESP8266 flammable gas alarm - part 3

This is the third part of the ESP8266 gas detector series. There have not been any changes hardware-wise. As promised in the previous video, part 2, the ESP board now becomes a simple IoT device, sending its data to a remote server via HTTPS. This solves the problem of security and performance. The software setup is now, of course, more complicated but it's worth it.
