Library to get readings from the DHT11, DHT22, and AM2302 humidity and temperature sensors on a Raspberry Pi or Beaglebone Black.

Project description

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

Currently the library is tested with Python 2.6, 2.7, 3.3 and 3.4. It should work with Python greater than 3.4, too.

Installing

### Dependencies

For all platforms (Raspberry Pi and Beaglebone Black) make sure your system is able to compile and download Python extensions with pip:

On Raspbian or Beaglebone Black’s Debian/Ubuntu image you can ensure your system is ready by running one or two of the following sets of commands:

Python 2:

``sh sudo apt-get update sudo apt-get install python-pip sudo python -m pip install --upgrade pip setuptools wheel ``

Python 3:

``sh sudo apt-get update sudo apt-get install python3-pip sudo python3 -m pip install --upgrade pip setuptools wheel ``

### Install with pip

Use pip to install from PyPI.

Python 2:

`sh sudo pip install Adafruit_DHT `

Python 3:

`sh sudo pip3 install Adafruit_DHT `

### Compile and install from the repository

First download the library source code from the [GitHub releases page](https://github.com/adafruit/Adafruit_Python_DHT/releases), unzipping the archive, and execute:

Python 2:

`sh cd Adafruit_Python_DHT sudo python setup.py install `

Python 3:

`sh cd Adafruit_Python_DHT sudo python3 setup.py install `

You may also git clone the repository if you want to test an unreleased version:

`sh git clone https://github.com/adafruit/Adafruit_Python_DHT.git `

Usage

See example of usage in the examples folder.
