Python library to read the DHT series of humidity and temperature sensors on a Raspberry Pi or Beaglebone Black.

Designed specifically to work with the Adafruit DHT series sensors ----> https://www.adafruit.com/products/385 It is also known to work with AM2302 based sensors.

This is a fork of https://github.com/adafruit/Adafruit_Python_DHT so that I could put a copy up on PyPi as this hasn't been done by the original author. In March, 2018 I handed ownership of the PyPi project https://pypi.org/project/Adafruit_Python_DHT/ to Adafruit

Currently the library is only tested with Python 2.6/2.7.

For all platforms (Raspberry Pi and Beaglebone Black) make sure your system is able to compile Python extensions. On Raspbian or Beaglebone Black's Debian/Ubuntu image you can ensure your system is ready by executing:

sudo apt-get update
sudo apt-get install build-essential python-dev

The library can be installed using pip

pip install adafruit_python_dht

or by downloading the source archive from:

PyPi https://pypi.python.org/pypi/Adafruit_Python_DHT

or

Github https://github.com/hexdump42/Adafruit_Python_DHT

expanding the archive, and executing:

sudo python setup.py install

You can test by using the script Adafruit_DHT which is installed as part of the distribution.

usage: sudo Adafruit_DHT [11|22|2302] GPIOpin#

example: sudo Adafruit_DHT 2302 4 - Read from an AM2302 connected to GPIO #4

See example of usage in the examples folder.
