Nr16 - DHT11 und DHT22 - Anleitungen und Kits fr Arduino

In this example, two boards are programmed to communicate with one another in a Master Writer/Slave Receiver configuration via the I2C synchronous serial protocol. Several functions of Arduino's Wire Library are used to accomplish this. Arduino 1, the Master, is programmed to send 6 bytes of data every half second to a uniquely addressed Slave.

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.
