DHT22 Sensor Pinout, Specs, Equivalents, Circuit Datasheet
The AM2302 can connect directly to the Arduino Uno. The AM2302(DHT22) temperature / humidity sensor cables are as follows: 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 …
DHT22 (AM2302) working with DHTLib and not with Adafruit
You must notice that AM2320 is not a DHT series and it requires I2C connection. This is very useful if you are using it for a weather station along with BMP180 which is also I2C. I tried several libraries with no success until I made it. So if you want to buy an AM2320 here is how to use it with Arduino.

How to Connect Simple Raspberry Pi with DHT11/DHT22/AM2302
How to Hookup DHT22 Temperature Sensor to Arduino Board. The DHT-22 is a low cost device for measuring humidity and temperature. The DHT sensors are made of two parts, a capacitive humidity sensor and a thermistor. The device requires a 3 to 5V power supply. It uses a single data wire to communicate back to the Arduino.
