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

Project Description

Adafruit Python DHT Sensor Library

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 ---->
It is also known to work with AM2302 based sensors.

This is a fork of so that I could put a copy up on PyPi as this hasn't been done by the original author.

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:




expanding the archive, and executing:

sudo python 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.
