import Adafruit_DHT as dht
import sys
pin = int(sys.argv[1])
sensor = dht.DHT11
humidity, temperature = dht.read_retry(sensor, pin)
if humidity is not None and temperature is not None:
    print '{0:d} {1:0.1f} c {2:0.1f} %'.format(0,temperature, humidity)
else:
    print '{0:d} {1:d} c {2:d} %'.format(3,0,0)
