Code

Raspberry Pi DH22 IOT

Python
The following code takes data collected from the dht22 temperature and humidity sensor and sends it to Ubidots where it can be viewed online.
from ubidots import ApiClient
import Adafruit_DHT
import RPi.GPIO as GPIO
import time

sensor = Adafruit_DHT.DHT22

pin = 4

humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
# Create an ApiClient object

api = ApiClient(token='blRKvyxIkkWGqVSWRqSya2pfGKogcB')

GPIO.setmode(GPIO.BCM)
GPIO.setup(1, GPIO.OUT)
GPIO.setup(7, GPIO.IN)
GPIO.setup(6, GPIO.OUT)
# Get a Ubidots Variable

try:
    variable1 = api.get_variable("5711025d76254250de6dac65")
    variable2 = api.get_variable("571ba07976254240aa73c7c7")

except ValueError:
    print"It is not possible to obtain the variable"

while(1):
    try:

        # sends data to ubidots.
        # temperature reading is in fahrenheit since thats what Americans         like

        value1 = (temperature)*1.8+32

        value2 = humidity

        variable1.save_value({'value': value1})
        variable2.save_value({'value': value2})

        print "Value sent"
        time.sleep(1)
    except ValueError:
        print "Value not sent"
