Raspberry_Pi_2_driver

[AsawariC]

Need help on 'How to install Raspberry_Pi_2_Driver?' I have searched for Raspberry_Pi_2_Driver but could not get relevant info. Following is the python code lines for programming DHT-22 sensor on Raspbery Pi 2 model B. Please give your suggestions on this.
code for DHT-22 sensor in python :
>>> import Adafruit_DHT
>>> Adafruit_DHT.read_retry(Adafruit_DHT.AM2302, '22')

Error encounter:
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
Adafruit_DHT.read_retry(Adafruit_DHT.AM2302, '22')
File "Adafruit_DHT/common.py", line 90, in read_retry
humidity, temperature = read(sensor, pin, platform)
File "Adafruit_DHT/common.py", line 76, in read
platform = get_platform()
File "Adafruit_DHT/common.py", line 51, in get_platform
import Raspberry_Pi_2
File "Adafruit_DHT/Raspberry_Pi_2.py", line 22, in <module>
import Raspberry_Pi_2_Driver as driver
ImportError: No module named Raspberry_Pi_2_Driver

How did you install the Adafruit_DHT module? Did you follow these instructions: https://github.com/adafruit/Adafruit_Python_DHT

I can see the driver you need in the "source" folder so I suspect it would be built when you run the necessary installation commands.

Thank you for the reply.
yes, I followed the instruction in the mentioned link.
Also found the driver in source folder and the code is in the same folder as the driver is in. still i get this error and don't know how to get rid of that error. could you suggest something?

Are you using python2 or python3?

You have to install external libraries twice, once for each flavour of python.

sudo python setup.py install
will use python2

sudo python3 setup.py install
will install it for python3 (if it's compatible)

[AsawariC]

Thank you for the reply.
I am using python2.
However, I tried installing external libraries twice as suggested but still getting the same ImportError: No module named Raspberry_Pi_2_Driver.
I am still trying to solve this..
If you could suggest me anything further on this, I would be very thankful.

Thank you very much for the reply.
I will do accordingly.

I had the same problem and found the solution!

Just make sure you are in the examples path

• pi@raspberrypi ~/Adafruit_Python_DHT/examples

Then run the program with

• sudo AdafruitDHT.py 22 23

where 22 means it is DHT22 and GPIO pin is 23


Hope this helps.

Hey,
same prob here - the script works when using it in the examples path. But why do they only work there? I actually wanted to move my scripts to /root.
