+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
