I just carefully followed the instruction in http://learn.adafruit.com/dht-humidity-sensing-on-raspberry-pi-with-gdocs-logging/overview and now it’s working ^_^.   I’ll be posting the GDocs file link soon 😀

Update 20130831 15:08: See the docs here https://docs.google.com/spreadsheet/ccc?key=0AruZq1bsDTVadGV3WUJsakwtUGNGMFB3aWxUdmMxc1E&usp=sharing

 

 

The Adafruit DHT library was written for AM2302 sensor… if you are using DHT11 sensor, you have to change the line 44 of “Adafruit_DHT_googledocs.ex.py” from:

  output = subprocess.check_output([“./Adafruit_DHT”, “2302”, “4”]);

to

  output = subprocess.check_output([“./Adafruit_DHT”, “11”, “4”]);

Then everything will work well 😀

Happy hacking!  ^_^
