MQ-135 CO2 Sensor part 2

Couple of updates since my latest post:

  • I added a new Wifi hotspot, called it ThaissaPatrickInternetOfThings, for all of my IOT gagdetery, since the girlfriend was complaining about the internet being slow because of all the devices connected to it.
  • Added a logic level converter since a collegue (you know who you are!) pointed out that the sensor operates at 5v and the Wemos at 3.3V
  • Took some pictures:
