This is an Arduino-library for easy reading of temperature/humidity sensors based on DHT11, DHT22 (aka Aosong AM2302).
The library is compatible with Arduino Software version 1.x as well as old 0.x.
Library is heavily based on publication at http://sheepdogguides.com/arduino/ar3ne1humDHT11.htm
Encapsulation in a reusable library, some code-size optimization and few fixes are done by Amperka Team (http://amperka.ru)
Copy lib/dht directory to /path/to/your/arduino-ide/libraries
Usage example is in src/example.ino
If you prefer to work in console and have ino installed:
# checkout the library
git clone git@github.com:amperka/dht.git
cd dht
# build, upload and run serial monitor
ino build
ino upload
ino serial
