AM2302 temperature / humidity sensor connected to an Arduino Uno through a Mini Breadboard

The AM2302 can connect directly to the Arduino Uno. I used the Mini Breadboard to allow me to add other connections afterwards.

The AM2302 temperature / humidity sensor cables are as follows (left to right with label facing you):

Red : +5v power connects to 5v power on Arduino Uno Yellow : Data connection connects to Pin 2 or 3 on Arduino Uno Black : Supplementary ground can connect to a GND on Arduino Uno but documentation says it is not necessary and can be left out White : Full ground connects to a GND on Arduino Uno

The major limitation I have read about is that the sensor can not take readings more rapidly than every 2 seconds. I have added a 3 second delay between readings to (hopefully) ensure precision.
