The DHT11, DHT21 and DHT22 are relative inexpensive sensors for measuring temperature and humidity.
This library can be used for reading both values from these DHT sensors.
The DHT11 only returns integers (e.g. 20) and does not support neagtive values.
The DHT22 and 21 are quite similar and provide one decimal digit (e.g. 20.2)
The hardware pins of the sensors and handshake are identical so ideal to combine in one lib.
The library is confirmed to work on:
UNO (tested myself)
2009 (tested myself)
MEGA2560
DUE
attiny85 @8MHz
Digistump Digix @ 84 MHz
