Arduino Wiring

You will need the following parts for this tutorial:

  • 1x Adafruit IO compatible Feather
  • 1x DH22 temperature & humidity sensor
  • 1x 10k ohm resistor
  • 4x jumper wires

We will need to connect the following pins from the Feather to the resistor and DHT22:

* Feather 3V to Pin 1 of the DHT22
* Feather 3V to one leg of a 10k ohm resistor, and the other leg of the resistor to Pin 2 of the DHT22
* Feather Pin 2 to Pin 2 of the DHT22
* Feather GND to Pin 4 of the DHT22
