 1 | # Raspberry Weather DHT22 
 2 | 
 3 | ## Introduction
 4 | 
 5 | This code helps you read temperatures along with humidity and save both in your database. You need to configure your weather station in order to use this code. Read more on www.raspberryweather.com.
 6 | 
 7 | The PressureWind branch (http://goo.gl/JXv3Ht) created by A. Catorcini is an expansion to the basic functionalities. Take a look if you want to display wind speed and barometric pressure!

 9 | ## Installation
10 | 
11 | First, you need to install the DHT22 library by Adafruit and some additional software:
12 | 
13 | > git clone https://github.com/adafruit/Adafruit_Python_DHT.git
14 | 
15 | > cd Adafruit_Python_DHT
16 | 
17 | > sudo apt-get update
18 | 
19 | > sudo apt-get install build-essential python-dev python-openssl
20 | 
21 | > sudo python setup.py install
22 | 
23 | If everything is wired correctly, test the setup with
24 | > sudo ./AdafruitDHT.py 22 4
25 | 
26 | Where 22 is the DHT22 sensor and 4 represents pin #4
