Raspberry Pi 3 - Model B+
The Raspberry Pi is a small linux board compatible with Adafruit IO projects.
If you're following along with a Raspberry Pi, we're going to use a T-Cobbler Plus for the IO Basics Projects. This add-on prototyping board lets you easily connect a Raspberry Pi (Raspberry Pi Model Zero, A+, B+, Pi 2, Pi 3) to a solderless breadboard:
Assembled Pi T-Cobbler Plus - GPIO Breakout
PRODUCT ID: 2028
This is the assembled version of the Pi T-Cobbler Plus. It only works with the Raspberry Pi Model Zero, A+, B+, Pi 2,Pi 3! (Any Pi with 2x20 connector)

We'll also need a temperature and humidity sensor. The DHT22 is a low-cost temperature and humidity sensor which is easy to wire up. You'll also need a 10k ohm resistor.
DHT22 temperature-humidity sensor + extras
PRODUCT ID: 385
The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital...

Make the following connections between the Pi and the DHT22:
- Pi 3.3V to DHT Pin 1
- Pi Digital Pin 26 to DHT Pin 2
- Pi GND to DHT Pin 4
- 10k ohm resistor (left pin) to DHT Pin 2
- 10k ohm resistor (right pin) to GND
