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.
