RaspberryPi with DHT11 Temperature and Humidity Sensor

DHT11 Sensor with 4.7K Resistor

 

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

Console Temperature and Humidity

 

DHT11 to GDocs

 

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!  ^_^
