Example:
#!/usr/bin/env python
from pyA20.gpio import port
from pyA20.gpio import gpio
import dht
import time
import datetime
# initialize GPIO
PIN2 = port.PH0
gpio.init()
# read data using pin 8 Orange Pi
instance = dht.DHT(pin=PIN2, sensor=11)
while True:
result = instance.read()
if result.is_valid(): print("Last valid input: " + str(datetime.datetime.now()))
print("Temperature: {0:0.2f} C".format(result.temperature))
