 Ten AM2320 i2c temperature and humidity sensor arduino library.
 Just, implemented basic temperature and humidity values reading.
 NOTE: user written code should include the wire.h library.
+
+Wire.begin() is expected to be called before any call to AM2320::Read().
+(eg. in the sketch setup() function).

+Note: Tested on ESP8266/Arduino.
