Loop - Raspberry Pi Forums

hello...

wrong whith code ? need play repeatedly. (reading dht22)

idea ?

code: select all

import sys  import adafruit_dht time import sleep   sensor_args = { '11': adafruit_dht.dht11,                 '22': adafruit_dht.dht22,                 '2302': adafruit_dht.am2302 } if len(sys.argv) == 3 , sys.argv[1] in sensor_args:     sensor = sensor_args[sys.argv[1]]     pin = sys.argv[2] else:     print('usage: sudo ./adafruit_dht.py [11|22|2302] gpiopin#')     print('example: sudo ./adafruit_dht.py 2302 4 - read am2302 connecte$     sys.exit(1)  humidity, temperature = adafruit_dht.read_retry(sensor, pin)   if humidity not none , temperature not none:     print('temp={0:0.1f}*  humidity={1:0.1f}%'.format(temperature, humidity)) else:     print('failed reading. try again!') sleep(30) 

thanks

there's no main loop.

code: select all

while (condition_goes here):    # stuff in main loop
