Primary LanguageCMIT LicenseMIT

Modified DHT Sensor library

Added compatibility

Modified Adafruit Python DHT Sensor library for Raspberry Pi 4 compatibility

Dependencies DEPRECATED LIBRARY Adafruit Python DHT Sensor Library

this library has been deprecated! We are leaving this up for historical and research purposes but archiving the repository.

We are now only supporting the use of our CircuitPython libraries for use with Python.

Check out this guide for info on using DHT sensors with the CircuitPython library: https://learn.adafruit.com/dht-humidity-sensing-on-raspberry-pi-with-gdocs-logging/python-setup

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:

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

Python 3:

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:

sudo pip install Adafruit_DHT

Python 3:

sudo pip3 install Adafruit_DHT

Compile and install from the repository

First download the library source code from the GitHub releases page, unzipping the archive, and execute:

Python 2:

cd Adafruit_Python_DHT
sudo python setup.py install

Python 3:

cd Adafruit_Python_DHT
sudo python3 setup.py install

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

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